Observation one: ->write_proc and ->data assignments aren't needed. Removed.
Observation two: codecs lists are unprotected. Patch doesn't fix this.
Observation three:
/proc/videocodecs printout is done to temporary _global_ buffer which
is freed in between. Consequently, two users hitting this file can
screwup each other.
Steps to reproduce:
modprobe videocodec
while true; do cat /proc/videocodecs &>/dev/null; done &
while true; do cat /proc/videocodecs &>/dev/null; done &
The fix is switching to seq_files, this removes code, especially some
line-length "logic".

struct video_device used to define a .hardware field. While
initialized on severl drivers, this field is never used inside V4L.
However, drivers using it need to include the old V4L1 header.
This seems to cause compilation troubles with some random configs.
Better just to remove it from all drivers.

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.

kernel-sync:
Kernel adds "-include include/linux/autoconf.h" for every file to be
compiled, so, including config.h is not required.

Now, drivers/media tree is complete. Only missing zoran36120
since this won't work and it is a good candidate to be removed
from kernel soon.
