[PATCH] v4l: (935) Moved common IR stuff to ir-common.c
- The pinnacle handler & remote are common to saa7134 PCI boards and em28xx USB boards, so the keymap was moved to ir-common and the keyhandler is back to ir-kbd-i2c - request_module("ir-kbd-i2c") is no longer necessary at saa7134-core since saa7134.ko now depends on ir-kbd-i2c.ko to get the keyhandler Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@brturbo.com.br> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
