The remaining drivers are mostly platform drivers. Name the
dir to reflect it.
It makes sense to latter break it into a few other dirs.

The correct place to put i2c_gate_ctrl is before calling tda18271_attach,
because the driver tda18271 will use it to enable or disable the i2c-bus
from the demodulator to the tuner.
And thus eliminate the error message: "Unknown device (255) detected
@ 1-00c0, device not supported" in the driver tda18271.
In the device kworld_sbtvd (hybrid analog and digital TV) the control
of the i2c-bus to tuner is done in the analog demodulator and not in
the digital demodulator.

This patch fixes the following sparse warnings
by removing use of duplicate const.
drivers/media/video/cx88/cx88.h:152:40:
warning: duplicate const
drivers/media/video/cx88/cx88-core.c:256:33:
warning: duplicate const
drivers/media/video/cx88/cx88-alsa.c:769:41:
warning: duplicate const
As commented by Jonathan Nieder:
These double "const" were introduced in v2.6.37-rc1~64^2~464 (V4L/DVB:
drivers/media: Make static data tables and strings const, 2010-08-25).
The address of an array is already immutable by definition, so for
what it's worth, with or without a clarified commit message,
[mchehab@redhat.com: Tested with "gcc -s" (version 4.7.0):
the produced asm is indeed equal before and after this patch]

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.

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.

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 was introduced on commit c2a6b54a9:
"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.
