V4L/DVB (7364): reduce stack usage of v4l_compat_translate_ioctl
v4l_compat_translate_ioctl used 1376 bytes of stack (x86_64), so split this 800 lines long function into ~20 small noinline functions; the biggest function takes now 712 bytes (v4l1_compat_sync) fix VIDIOCSWIN handler which printked wrong errors Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
