The commands CX2341X_DEC_SET_AUDIO_OUTPUT, CX2341X_DEC_SET_AV_DELAY and
CX2341X_ENC_SET_3_2_PULLDOWN are not implemented in the Conexant firmware.
So these commands are removed. This also means that the V4L2_CID_MPEG_VIDEO_PULLDOWN
control in cx2341x.c and pvrusb2-hdw.c is removed.

The temporal filter is forced off when scaling. The VIDIOC_LOG_STATUS
handler still showed the old temporal filter. It is now consistent with
the real temporal filter value.

Change the code to unconditionally turn off the temporal filter when scaling.
If the window is not full screen the filter will introduce a nasty ghosting
effect.

The wrong matrix was used when an external input was selected instead of
the tuner input. The rxsubchans field was also not initialized to STEREO
for an external input. And finally the msp34xxg_detect_stereo() should
not try to detect stereo for an external input, that code is for the
tuner input only.
Together these bugs made it hit 'n miss whether you ever got stereo out
of the msp3400 for an external input.

On cx88 driver, sampling rate should be at chroma subcarrier freq (FSC).
However, driver were programming wrong values for PAL/60, PAL/Nc and
NTSC 4.43. This patch do the proper calculation. It also calculates
htotal, hdelay and hactive constants, according with the sampling
rate.
It is tested with PAL/60 by Piotr Maksymuk and Olivier. Test is still
required for PAL/Nc.

- SYSFS: Replaced all to_video_device(cd), video_device_create_file,
video_device_remove_file and add the proper checks at create_file
- Converted old norm values to V4L2 ones.
- Robustness on sysfs hue/contrast/saturation queries.
Additional check in order to return 0 if the driver is not opened.
- Clean up of white spaces in usbvision.h
This patch merges two fixes by Thierry MERLE and Mauro Chehab, and adds
additional checks.

Main changes:
- There were several checks for usb release routines that were removed, since
the routine itself checks for null values:
usb_free_urb, usb_kill_urb, usb_unlink_urb
Should be checked if this really happens on older kernels.
- updated sound/oss/btaudio.c
- replaced SLAB_ATOMIC to GFP_ATOMIC

Run this:
============== cut here ==============
for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
echo "De-casting $f..."
perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
done
And then go through and reinstate those cases where code is casting pointers
to non-pointers.
And then drop a few hunks which conflicted with outstanding work.

There was a still a pre-dvb-pll set_params function for the lgdt3302 in
the cx88-dvb driver. This patch removes that function and uses
dvb_pll_attach() for the cards that were using it (Dvico FusionHDTV 3
GOLD {Q,T}). This way the set_params function from dvb-pll is used.
dvb_attach() is in turn used on dvb_pll_attach(), eliminating some static
dependencies on dvb-pll. There are still a couple static dependencies on
dvb-pll remaining.
