V4L/DVB (6793): Convert saa7134-empress to video_ioctl2
saa7134 were converted to video_ioctl2, but saa7134_empress weren't. This broke saa7134-empress, since it were dependent of saa7134_common_ioctl. With the conversion, the module had a size decrease of 436 bytes on x86_64: text data bss dec hex filename 5196 4912 4 10112 2780 old/saa7134-empress.ko 4760 4912 4 9676 25cc new/saa7134-empress.ko Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
