[GIT PATCHES FOR 3.1] New SE401 driver + major pwc driver cleanup

[Hans de Goede <hdegoede@redhat.com>]

Hi All,

I'm happy to present my latest webcam work to you:

I could not just stand by watching the old v4l1 se401 driver
(which has been broken for a long while btw) get removed
from the kernel, without writing a replacement, so I'm
happy to present a new, actually working, gspca based
v4l2 driver for se401 based webcams :)

I've also wanted to do some much needed cleanups to the
pwc driver for a long while. When I finally started with
this I ended up with just replacing large parts with
the new v4l2 framework, so after this patch set pwc
now features:
-videobuf2 for buffer management
-ctrls handled by the control framework, including proper
  setting inactive of foo controls when autofoo is on, etc.
-new v4l2 controls for pan/tilt on models with pan/tilt
  to replace the non standard sysfs interface for this

May I also point your attention to the
feature-removal-schedule commit, which adds a whole bunch
of custom pwc API's / ioctls for removal, since we can
handle this all fine with v4l2. If you think some of
these should not be removed speak up now, or hold
your silence for ever :)
