Add support for Magic-Pro DMB-TH usb stick.  DMB-TH is the HDTV broadcast
standard used in Hong Kong and China.
[...]
I've also attached a second patch against the dvb-apps repository which
adds a DMB-TH scan file for Hong Kong.

Since the ProHDTV stick contains a DMB-TH decoder (lgs8gl5) onboard,
it outputs MPEG-TS to the PC.

Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4
which has new tuners and demodulators (2 x DIB7070p). With this patch
both DVB reception and IR works.

The dib7000p driver currently hardwires the output mode to
OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow
OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the
check completely and set the output mode correctly in all the callers.

Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled.
It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but
this is what the other DIB7070 module does (there are a number of
module dependencies in the attach code).

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.

It seems cosmetically better to let USB drivers be the last one.

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.

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.]
