This callback were meant to allow overriding a FE callback, before its
call, but it is not really needed, as the callback can be intercepted
after tuner attachment.
Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5
application will produce different effects than a DVBv3 one.
So, get rid of it.

The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove

In two cases, the original memory allocation function was kmalloc, which
has been changed to a zeroing allocation to benefit from the devm function.

This simplies the code and resolves a possible race condition between
ir_raw_decode_timer_end() and saa7134_raw_decode_irq().
If the interrupt handler is called after ir_raw_decode_timer_end()
calls ir_raw_event_handle() but before clearing ir->active, then the
timer won't be rearmed.
Compile tested only.

The TechnoTrend USB IR Receiver sends 125 ISO URBs per second, even when
there is no IR activity. Reduce the number of wake ups from the other
drivers too.
This saves about 0.25ms/s on a 2.4GHz Core 2 according to powertop.

The Pioneer CU-700 remote causes receiver overflows if you hold down any
button. The remote does not send NEC IR repeats, it repeats the entire
NEC code after 20ms.
The iguanair hardware advertises an interval of 10 which just not enough;
with 100 URBs per second and at most 7 edges per URB, we handle at most
700 edges per second. The remote generates about 900.

This driver adds support for stk1160 usb bridge as used in some
video/audio usb capture devices.
It is a complete rewrite of staging/media/easycap driver and
it's meant as a replacement.
As stk1160 allows communication with an ac97 codec chip, this
driver allows to register a control-only sound card to allow the user
to access ac97 controls.
Two devices have been used for testing:
* 1-cvbs video and 1-audio ac97 input,
* 4-cvbs inputs
Both of these devices reports with the same id [05e1:0408],
so the driver tries to support a superset of the capabilities.
By using keep_buffers module parameter it's possible to prevent
the driver from releasing urb buffers when streaming is stopped.
The usage of this parameter can avoid memory fragmentation that may
cause the driver to stop working on low memory systems.
A similar mechanism is implemented in em28xx driver (see commit 86d38d).

This DVB_FE_IOCTL_POST isn't used, so remove it.
Also, intercepting ioctl's like that only works with legacy ioctl's,
due to the way it was implemented. so this design is broken.

"em28xx: fix: don't do image interlacing on webcams"
The proposed patch by Ezequiel is wrong. The right fix here is to just
don't bother here if either the image is progressive or not.
