has_tuner flag doesn't make much sense, since tuner_type=TUNER_ABSENT
means the same thing.
Having two ways to say that a tuner is not present is
not nice, since it may lead to bad setups. In fact, with the previous
code, if a device were using has_tuner=0, but the user forces a tuner,
with modprobe option tuner=type, the modprobe option won't work.
Also, tveeprom returns TUNER_ABSENT, when tuner is unknown or absent.
So, with the previous logic, in this case, the driver should set
has_tuner=0, or has_tuner=1 otherwise.
Instead of adding several additional tests and setups, better just to
remove .has_tuner.

Older em28xx devices does implement standard Audio Class.
However, on newer devices, this were replaced by a Vendor Class. This
patch autodetects that an em28xx lacks Audio Class and auto-loads
em28xx-alsa, for the devices that implements only a Vendor Class.
For devices with Audio Class, snd-usb-audio module will provide an ALSA
interface.
This patch uses the request_module_async function as defined on cx88-mpeg.c,

Xc2028.3028 has two type of firmwares: audio-standard specific ones and
baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz
BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares.
It seems that the option to use MTS or a standard-specific audio decoding
depends on the way xc2028/3028 is connected.
Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS
firmware, this patch converts it to a bitfield that can be shared with other
proprieties of xc2028/3028.

The attached patch modifies the em28xx driver so that there can be ioctls from
multiple different threads.
This is necessary for capture apps like MPlayer that use different threads for
capturing and channel tuning.
Now the locking is only done for the ioctls that change properties of the
device or access the i2c bus.
It also removes some locks that look unnecessary:
In em28xx_init_dev:
the videodevice is not registered yet so nothing can access the hardware
meanwhile, the device struct is not assigned to the interface yet so no race
with disconnect is possible
In em28xx_release_resources:
it gets only called when dev->lock is already held

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

There are several boards on V4L that can work with several different

This patch adds the capability of choicing between autoselecting the

Most uses a tda988[5/6/7] IF demodulator as part of the device.
Having this as a separate stuff makes harder to configure it, since there
are some tda9887 options that are tuner-dependent and should be bound into
tuner-types structures.
This patch merges tda9887 module into tuner. More work is required to make
tuner-types to properly use it.
