![Mauro Carvalho Chehab](/assets/img/avatar_default.png)
Tested on x64 with a bttv board. Most Get ioctls are fixed. The only non-completely working one is VIDIOCGAUDIO. All other IOR ioctls give the same results on x86_64 and i386 architectures. Thanks to Alastair Poole <netstar@gatheringofgray.com> for part of this patch and tests on ppc64.
