Hi Stephen,
Thanks for pointing it. It took me some time, but I applied today
a bunch of patches that are fixing all warnings on everything
at drivers/media and drivers/staging/media, with:
make ARCH=i386 W=1
(allyesconfig, gcc 4.7.2)
Maybe there are still a few ones with random configs and other
archs, but at least on my usual testing environment, we're
warnings-free on drivers/media for now, probably up to the
next gcc version.
