Andy Walls b757730b02 [media] lirc_zilog: Update IR Rx polling kthread start/stop and some printks
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
ir_probe() function.

Andy Walls a68a9b73fb [media] lirc_zilog: Extensive rework of ir_probe()/ir_remove()
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.

Andy Walls e9b351f64f [media] lirc_zilog: Don't make private copies of i2c clients
Don't make private copies of the i2c clients provided by the I2C
subsystem, don't change the client address field, and don't probe
the client addresses - the bridge driver already did that.  This
moves us to the proper I2C and binding model.

Andy Walls 06da95a3ec [media] lirc_zilog: Split struct IR into structs IR, IR_tx, and IR_rx
This change is a mostly mechanical break of the main struct IR
data structure into common, Rx, and Tx structures.  There were some
small logical changes required as well, such as eliminating "is_hdpvr",
to accomplish this.

This change is an intiial step in reworking lirc_zilog to decouple the
Rx and Tx handling as much as possible to fit with the new I2C
binding model.  This change actually makes lirc_zilog a little more
broken than it already was - memory deallocation in particular got worse.
However, this change makes the remaining problems easier to see and address.

The only reason to use the lirc_zilog module is for IR Tx, so remove

Jarod Wilson 76f1ef427c [media] rc/imon: default to key mode instead of mouse mode
My initial thinking was that we should default to mouse mode, so people
could use the mouse function to click on something on a login screen,
but a lot of systems where a remote is useful automatically log in a
user and launch a media center application, some of which hide the
mouse, which can be confusing to users if they punch buttons on the
remote and don't see any feedback. Plus, first and foremost, its a
remote, so lets default to being a remote, and only toggle into mouse
mode when the user explicitly asks for it. As a nice side-effect, this
actually simplifies some of the code a fair bit...

Jesper Juhl fd01ad9894 [media] media, tlg2300: Fix memory leak in alloc_bulk_urbs_generic()
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.

Hans Verkuil 45f6f84af3 [media] v4l2-subdev: add (un)register internal ops
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 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.

Mauro Carvalho Chehab c736a5f28e [media] mb86a20s: Be sure that device is initialized before starting DVB
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.

This happens because some I2C callbacks actually depend on having the
driver entirely initialized. To avoid this OOPS, just clean the I2C
callbacks, as if no device were detected.

Mauro Carvalho Chehab 567aba0b79 [media] tda8290: Make all read operations atomic
Read operations should be preceeded by a write operation. However,
nothing prevents that an I2C operation could happen between the two
transactions.

To avoid that problem, use an unique I2C transfer for both parts of
the I2C transaction.

Mauro Carvalho Chehab 59aa346009 [media] dib0700: Fix IR keycode handling
Fixes Fedora 14 bug: https://bugzilla.redhat.com/show_bug.cgi?id=667157

There are a few bugs at the code that generates the scancode at dib0700:
	- RC keycode is wrong (it outputs a 24 bits keycode);
	- NEC extended outputs a keycode that have endiannes issues;
	- keycode tables for NEC extended remotes need to be updated.

The last issue need to be done as we get reports, as we don't have
the complete NEC-extended keycodes at the dibcom table.

This patch fixes the first two issues.

Hans Verkuil a1198ccf9c [media] v4l2-ioctl: fix incorrect error code if VIDIOC_DBG_G/S_REGISTER are unsupported
The ioctls VIDIOC_DBG_S_REGISTER and VIDIOC_DBG_G_REGISTER should return -EINVAL
if the driver didn't implement them. Currently they return -EPERM if called as
non-root user. However, this check should only be done if the driver actually
implemented these ioctls. Otherwise, just return -EINVAL as we do with all
unimplemented ioctls.

This bug make the v4l2-compliance test suite fail.
