Tuners currently hook different things to the private pointer in their
callback function. Longer term we should make that private pointer
consistent, but for now separate out the guts of the cx23885 tuner callback
so we can reuse it.

v4l2_ctrl_query_menu_valid_items() makes it easy to handle control menus
that have a lot of invalid 'holes'. For example, many MPEG encoders only
support a limited subset of audio bitrates. In that case a driver can

This patch adds the capability of decoding NEC protocol, received via GPIO18 line.
This GPIO port can trigger saa7134 IRQ.

A future improvement would be to make it a little more generic to work also
with GPIO16 line.

A pure IRQ code didn't work, since some delays were introduced on the tests we
did.

A possible approach would be to use polling at a rate of 2.5 ms or less. If a
new code were taken, a code similar to nec_task() could be used. However, this
would add an extra overhead to kernel, and will consume more power.

Due to that, we took an hybrid approach: an IRQ upper half to trigger when a
new key is received and a bottom half to convert pulse-distance into a keycode.

The bottom half is polling based, to improve performance. During the bottom
half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and
improving performance a little bit.

The BKL is now moved from the video_open function in v4l2-dev.c to the

lock of some sort protecting the open(), another third uses

BKL in their open function.

Also, two SOC drivers were using select, instead of depends on SOC_CAMERA.

Since select has some drawbacks when checking for dependencies, convert those
two into depends on.

INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975

A fixed size 8-byte buffer is allocated, and a variable size field is read
into it; there is no particular bound on the size of the field (it is
dependent on hardware and configuration) and it can overflow [also
verified by inserting printk's.]

Furthermore the s5h1420-driver is now doing the same i2c-method as it was done

The zr36067 driver should return the actual bytes-per-line value when
queried with ioctl VIDIOC_G_FMT, instead of 0. Otherwise user-space
applications can get confused.

Likewise, with ioctl VIDIOC_S_FMT, we are supposed to fill the
bytes-per-line value. And we shouldn't fail if the caller sets the
initial value to something different from 0. This is perfectly valid
for applications to pre-fill this field with the value they expect.
