Follows the same coding style for commented code
The latest patch series added a different way of commenting unused patches:
#ifdef notdef
But V4L/DVB coding style uses, instead:
#if 0
This have also the advantage of not sending to mainstream those development codes
that doesn't make sense at a production environment, while keeping them under
development trees.

Tweak the encoder setup in order to stop it from corrupting the video
data when there is a disruption in the data flow (e.g. a channel change).

This is a maintainability cleanup; use nice names for all the FX2
commands instead of raw bytes. This way we can easily find where we
issue FX commands.

Clean up and tighten logic involving stream configuration. This
mainly involves changes to pvrusb2-v4l2.c, where we better clarify how
we use the stream configuration enum and implement a cleaner means to
control streaming for a given device node.

This is the logic that supports switching modes via e.g.,
echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val.
To do the mode switching we need to a) broadcast AUDC_SET_RADIO and
b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is
done by adding a new pvr2_i2c_op and having it trigger on input change,
the second by adding this command in pvr2_encoder_start() and requesting
an encoder restart on input change by setting stale_subsys_mask appropriately.
The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided
by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode
switching this way (on input change) is due to Mike Isely.
Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but
I think this can be traced to a cornell student being the first to implement
radio support in ivtv "as a different standard". I think the rest just evolved
from there (it 's in the ivtv ML archives).

Tweak cx23416 configuration to permit xawtv to work again. This
problem was introduced when the model 24xxx hardware support was
added. The fix here repairs the problem while and is valid for both
old and new hardware.

Clean up logic for handling video standards in the pvrusb2 driver.
New implementation should be able to handle all possible V4L defined
video standards now, and it should be far easier to maintain this
going forward.

Rework entire internal controls interface to eliminate the need for
visibly defined control IDs which must otherwise be translated by the
V4L2 public interface. As part of this work, internal structures
which mimiced various V4L2 structures (video standards, audio modes)
have been reworked to actually use the native structures. This
triggered a _significant_ rework for how video standards are dealt
with (and what is in place now should be much more flexible and
forgiving for various handling less-common video standards).

This applies some changes to the logic which controls the cx23416 in
pvrusb2. This is required in order for newer model 24xxx hardware to
operate correctly and is backwards compatible with older hardware.
