V4L/DVB (7856): cx18/: possible cleanups
This patch contains the following possible cleanups: - cx18-i2c.c should #include "cx18-i2c.h" for getting the prototypes of it's global functions - make the following needlessly global functions static: - cx18-fileops.c:cx18_claim_stream() - cx18-fileops.c:cx18_release_stream() - cx18-queue.c:cx18_queue_move() - remove the following unused functions: - cx18-driver.c:cx18_waitq() - cx18-queue.c:cx18_buf_copy_from_user() Signed-off-by: Adrian Bunk <bunk@kernel.org> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
