PCI PM suspend callback took down the interface and resume brought
it back up. In the mac80211 context this is done in subsequent calls.
Rework implementation so that suspend only stores config, and sets
PCI power state. The resume return to full power state (D0), restores
the config, and brings hardware back up. Full bringup is done by
subsequent mac80211 calls.

The driver assumed it would receive skb packets from MAC80211 which
are not cloned. To guard this assumption an assert was placed in
the transmit routine. As of kernel 2.6.37 it turns out MAC80211 does
pass skb packets that are cloned. The assert is also not needed as
it does not lead to a failure state in our driver when the packet is
cloned. Therefore the assert can safely be removed.

those were corrected as well.

In cases where RTC hardware does not support alarms, the virtualized
RTC interfaces did not have a way to propagate the error up to userland.
This patch extends rtc_timer_enqueue so it catches errors from the hardware
and returns them upwards to the virtualized interfaces. To simplify error
handling, it also internalizes the management of the timer->enabled bit
into rtc_timer_enqueue and rtc_timer_remove.
Also makes rtc_timer_enqueue and rtc_timer_remove static.

Commit ca9b600be3 ("ACPI / PM: Make suspend_nvs_save() use
acpi_os_map_memory()") attempted to prevent the code in osl.c and nvs.c
from using different ioremap() variants by making the latter use
acpi_os_map_memory() for mapping the NVS pages. However, that also
requires acpi_os_unmap_memory() to be used for unmapping them, which
causes synchronize_rcu() to be executed many times in a row
unnecessarily and introduces substantial delays during resume on some
systems.
Instead of using acpi_os_map_memory() for mapping the NVS pages in nvs.c
introduce acpi_os_ioremap() calling ioremap_cache() and make the code in
both osl.c and nvs.c use it.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

If there are active requests for which we expect

This makes it possible to set an upper bound on

Regression since commit 1038953674, "firewire: core: check for 1394a
compliant IRM, fix inaccessibility of Sony camcorder":
The camcorder Canon MV5i generates lots of bus resets when asynchronous
requests are sent to it (e.g. Config ROM read requests or FCP Command
write requests) if the camcorder is not root node. This causes drop-
outs in videos or makes the camcorder entirely inaccessible.
https://bugzilla.redhat.com/show_bug.cgi?id=633260
Fix this by allowing any Canon device, even if it is a pre-1394a IRM
like MV5i are, to remain root node (if it is at least Cycle Master
capable). With the FireWire controller cards that I tested, MV5i always
becomes root node when plugged in and left to its own devices.

This partially reverts commit da8aeb92d4
("ACPI / Battery: Update information on info notification and resume"),
which causes a hang on resume on at least some machines.
This bug was bisected on an ASUS EeePC 901, which hangs at resume time
if we do that "acpi_battery_refresh(battery)" in the battery resume
function.
Rafael suspects we'll still need to refresh the sysfs files upon resume,
but that that can be done from a PM notifier (that will run after
thawing user space).

The ni_labpc driver module only requests a shared IRQ for PCI devices,
requesting a non-shared IRQ for non-PCI devices.
As this module is also used by the ni_labpc_cs module for certain
National Instruments PCMCIA cards, it also needs to request a shared IRQ
for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus

IVA MMU can manage up to 4GB of address space through its page tables,
given that it's L1 is divided into 1MB sections it requires at least
16KB for its table which represents 4096 entries of 32 bits each.
Previously, only 1GB was being handled by setting the page table size
to 4KB, any virtual address beyond of the L1 size used, would fall
into memory that does not belong to L1 translation tables, leading to
unpredictable results.
So, set the L1 table size to cover the entire MMU range (4GB) whether
is meant to be used or not.

During suspend, Linus found that his machine would hang for 3 seconds,
and identified that intel_ring_buffer_wait() was the culprit:
"Because from looking at the code, I get the notion that
"intel_read_status_page()" may not be exact. But what happens if that
inexact value matches our cached ring->actual_head, so we never even
try to read the exact case? Does it _stay_ inexact for arbitrarily
long times? If so, we might wait for the ring to empty forever (well,
until the timeout - the behavior I see), even though the ring really
_is_ empty."
As the reported HEAD position is only updated every time it crosses a
64k boundary, whilst draining the ring it is indeed likely to remain one
value. If that value matches the last known HEAD position, we never read
the true value from the register and so trigger a timeout.

The size I've chosen for the buffer is the maximum size I could
ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit
of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up
to 128).
Note that this might also remedy user reports of very sluggish behavior

A number of things going on here, but the end result is that the IR part
on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or
lirc_zilog.
First up, there are some conditional build fixes that come into play
whether i2c is built-in or modular. Second, we're swapping out
i2c_new_probed_device() for i2c_new_device(), as in my testing, probing
always fails, but we *know* that all hdpvr devices have a z8 chip at
0x70 and 0x71. Third, we're poking at an i2c address directly without a
client, and writing some magic bits to actually turn on this IR part
(this could use some improvement in the future). Fourth, some of the
i2c_adapter storage has been reworked, as the existing implementation
used to lead to an oops following i2c changes c. 2.6.31.
Earlier editions of this patch have been floating around the 'net for a
while, including being patched into Fedora kernels, and they *do* work.
This specific version isn't yet tested, beyond loading ir-kbd-i2c and
confirming that it does bind to the RX address of the hdpvr.

Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced
after it was freed.
Normally the i2c adapter is removed before this function is called. Removing
the adapter will also unregister all subdevs on that adapter, so generally
v4l2_device_unregister has nothing to do. However, in the case of a platform
i2c bus that bus is generally not freed.
In that case, after freeing the i2c subdevice the code will fall into the
second block when it tests if the subdev is a SPI device. But by that time
the subdev is already freed and the kernel oopses.
The fix is trivial: continue with the loop after freeing the i2c or spi
subdevice.

The IR Rx polling thread was originally a kernel_thread long ago,
and had only been minimally converted to a kthread. This patch
finishes that conversion by
- cleaning up all the unneeded completions
- destroying the kthread properly by calling kthread_stop()
- changing lirc_thread() to test kthread_should_stop() just before
every point where it may sleep
- reorganizing the lirc_thread() function so it uses fewer lines
- modifying the name of the kthread from "lirc_zilog" to
"zilog-rx-i2c-N", so ps will show which kthread polls
which Zilog Z8 IR unit.
Also some minor tweaks were made to logging emitted by the

This patch is an extensive rework of the ir_probe() and ir_remove() functions.
It removes all the double binding and allocation problems on module load.
It removes almost all the memory leaks on module exit and on device
instantiation failure. Proper destruction of the Rx polling kthread still
needs investigation and more work, but it is no worse than it already was.
This rework also had side effects that include:
- encapsulation of the ir_devices[] array
- serialization of access to the ir_devices[] array
- semantic change of the module parameter "disable_rx" to "tx_only"
If tx_only is true, the module does not claim the i2c_client for the IR Rx
function, and only claims and handles the i2c_client for the IR Tx function.
This is a first step in providing the option of letting ir-kbd-i2c.c handle
IR Rx function, while lirc_zilog handles the IR Tx function.

Hi,
While reading
drivers/media/video/tlg2300/pd-video.c::alloc_bulk_urbs_generic() I
noticed that
- We don't free the memory allocated to 'urb' if the call to
usb_alloc_coherent() fails.
- If the 'num' argument to the function is ever <= 0 we'll return an
uninitialized variable 'i' to the caller.
The following patch addresses both of the above by a) calling
usb_free_urb() when usb_alloc_coherent() fails and by explicitly
initializing 'i' to zero.
I also moved the variables 'mem' and 'urb' inside the for loop. This does
not actually make any difference, it just seemed more correct to me to let
variables exist only in the innermost scope they are used.

Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.
It is expected that in the future open and close ops will also be added.

The core.s_config op was meant for legacy drivers that needed to work with old

incorrectly called from several drivers.
Replace those occurences with proper i2c_board_info structs and call
v4l2_i2c_new_subdev_board.

The problem is that mb86a20s is only visible if the analog part is disabled.
However, due to a trick at mb86a20s, it will later initialize properly:
mb86a20s: mb86a20s_initfe: Initialization succeded.
This is hacky and ugly. However, I coldn't find any easy way to fix it.
A proper fix would be to have a resource locking schema, used by both
V4L and DVB parts that would block access to analog registers while
digital registers are in use, but this will probably put tda829x into
a dead lock.

There were some issues at tda8290 that were preventing this device
to work. Now that those fixes were fixed, we can enable analog
mode.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
Due to a hard to track bug between tda829x/tda18271/saa7134, tda829x
wants to go to analog mode during DVB initialization, causing some
I2C errors.
The analog failure doesn't cause any harm, as the device were already
properly initialized in analog mode. However, the failure at the digital
mode causes the frontend mb86a20s to not initialize. Fortunately, at
least on my tests, it was possible to detect that the device is a
mb86a20s before the failure.
What happens is that tda8290 is a very bad boy: during DVB setup, it
keeps insisting to call tda18271 analog_set_params, that calls
tune_agc code. The tune_agc code calls saa7134 driver, changing the
value of GPIO 27, switching from digital to analog mode and disabling
the access to mb86a20s, as, on Kworld SBTVD, the same GPIO used
to switch the hardware AGC mode seems to be used to enable the I2C
switch that allows access to the frontend (mb86a20s).
So, a call to analog_set_params ultimately disables the access to
the frontend, and causes a failure at the init frontend logic.
This patch is a workaround for this issue: it simply checks if the
frontend init had any failure. If so, it will init the frontend when
some DTV application will try to set DVB mode.
Even being a hack for Kworld SBTVD to work, and assumning that we could
teach tda8290 to be a good boy, this is actually an improvement at the
frontend driver, as it will be more reliable to initialization failures.

Looking at the windows inf file, for usb ids with a sensor type where probing
is needed to determine the type (for example ov7630 or soi768), this is
needed for all bridge variants with a usb id indicating this sensor type.
So do the probing to determine the actual sensor type for types where the
usb-id info is not 100% deterministic, independent of the bridge type.
If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and
0c45:612e (sn9c110 + ov7630), which according to the inf file can have a
soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.
The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.
This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

Before this patch we were not setting the memory type to GSPCA_MEMORY_NO
when the buffers were released by the app doing a reqbufs 0. Nor would
the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file
already is NULL on device close because of the reqbufs 0. This caused the
following problem:
-app1 does reqbufs USERPTR for 4 buffers
-app1 does reqbufs USERPTR for 0 buffers
-app2 tries to do reqbufs MMAP for 4 buffers
fails because gspca_dev->memory still is USERPTR
Fixing this also allows an app to switch memory type's by unrequesting
the buffers and re-requesting them of a different type.
This patch also moves the setting of gspca_dev->frsz and gscpa_dev->memory
to after alloc_frame succeeding, so that they are not changed when allocating

In commit 411674fd18 the tda9875 support was

If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.
The original commit message read as follows:
This change allows bttv to use tvaudio for this device. Since this device
has the same i2c address as the tda9874 we need to support both in the same
tvaudio driver. This makes it possible for tvaudio to detect which chip is
used. Originally the tda9875 was only available in the dedicated tda9875
driver, but that makes life very hard for bttv since loading tvaudio might
misdetect a tda9875 as a tda9874.
So there were good reasons for moving the tda9875 code into tvaudio.

unlikely to be at this point, and later dereference it. This will go bad
