cx88 only depends on VIDEO_IR because it needs ir_extract_bits().
Move that function to ir-core.h and make it inline.
Lots of drivers had dependencies on VIDEO_IR when they really
wanted IR_CORE.
The only remaining drivers to depend on VIDEO_IR are bt8xx and
saa7134 (ir_rc5_timer_end is the only function exported by
ir-functions).
Rename VIDEO_IR -> IR_LEGACY to give a hint to anyone writing or
converting drivers to IR_CORE that they do not want a dependency
on IR_LEGACY.

This patch removes the remaining usages of the ir_input_nokey() and
ir_input_keydown() functions provided by drivers/media/IR/ir-functions.c
by using the corresponding functionality in ir-core instead.

This patch converts the cx88 driver (for sampling hw) to use the
decoders provided by ir-core instead of the separate ones provided
by ir-functions (and gets rid of those).
The value for MO_DDS_IO had a comment saying it corresponded to
a 4kHz samplerate. That comment was unfortunately misleading. The
actual samplerate was something like 3250Hz.
The current value has been derived by analyzing the elapsed time
between interrupts for different values (knowing that each interrupt
corresponds to 32 samples).
Thanks to Mariusz Bialonczyk <manio@skyboo.net> for testing my patches
(about one a day for two weeks!) on actual hardware.

Because some clients (e.g. tvtime) will just open the filehandle and call
read() instead of explicitly calling streamon first, we need to make sure the
VBI timeout routine gets enabled in this case.

We need the au0828 to continue delivering frames even when the device is not
delivering video, or else applications such as tvtime will block indefinitely.
Unfortunately, the au8522 doesn't have any sort of free-running mode or "blue
screen on no video" like some other decoders.

We had the max packets per URB set to an incredibly low "10" as opposed to

The chip's default value for the brightness didn't match what we were sending
back in the queryctrl ioctl(), so if the application actually set the
brightness to the "default", it would actually end up being way too bright.

The following usb bandwidth allocation changes were made to the ibm netcam
pro code:
- Don't restart negotiation at max packet size on stop0, as that gets called
by gspca_main during negotiation. Move this to sd_isoc_init.
- Don't ask for full bandwidth when running at 160x120, that does not need
full bandwidth
- Make minimum acceptable bandwidth depend upon resolution

Currently alloc_and_submit_int_urb() is setting gspca->int_urb
as soon as the allocation has succeeded, but if the subsequent
submit fails, the urb gets destroyed. And then later will
get destroyed again in gspca_input_destroy_urb() because
gspca->int_urb is set, leading to a double free.

Currently gspca supported usb-1.1 webcams for which we support the input
button through an interrupt endpoint won't stream (not enough bandwidth
error) when used through an USB-2.0 hub.
After much debugging I've found out that the cause for this is that the
ehci-sched.c schedeling code does not like it when there are already urb's
scheduled when (large) isoc urbs are queued. By moving the submission
of the interrupt urbs to after submitting the isoc urbs the camera
starts working again through usb-2.0 hubs.
Note that this does not fix isoc. streaming through a usb-hub while another
1.1 usb device (like the microphone of the same cam) is also active
at the same time :(
I've spend a long time analyzing the linux kernel ehci scheduler code,
resulting in this (long) mail:
http://www.spinics.net/lists/linux-usb/msg37982.html
The conclusion of the following mail thread is that yes there are several
issues when using usb-1.1 devices through a usb-2.0 hub, but these are not
easily fixable in the current code. Fixing this in ehci-sched.c requires
an almost full rewrite, which is not bound to happen anytime soon.
So with this patch gspca driven usb-1.1 webcams will atleast work when
connected through an usb-2.0 hub when the microphone is not used.
As an added bonus this patch avoids extra destroy/create input urb cycles
when we end up falling back to a lower speed alt setting because of bandwidth
limitations.

If you suspend and resume during video capture, the video colours
are corrupted on resume. This is because the sensor is being unconditionally
powered off during the resume path.
Only power down during resume if the camera is not in use, and correctly

On our tests with Leadership ISDBT, the s921 frontend were not work. As its
design contained some weird things, it ended to be easier to just re-write
it, getting another frontend as an example (cx24123).
As the old s921 driver weren't used, there's no regression. Some info from
the old frontend were used as a way to double check the behavior that were
noticed on the USB dumps retrieved from Leadership driver.

Video drivers request submodules using a work during probe and calls
flush_scheduled_work() on exit to make sure the work is complete
before being unloaded. This patch makes these drivers flush the work
directly instead of using flush_scheduled_work().
While at it, relocate request_submodules() call in saa7134_initdev()
right right before successful return as in other drivers to avoid
failing after the work is scheduled and returning failure without the
work still active.
This is in preparation for the deprecation of flush_scheduled_work().
