V4L/DVB: media: ir-keytable: null dereference in debug code
"ir_dev->props" can be NULL. We only use raw mode if "ir_dev->props" is non-NULL and "ir_dev->props->driver_type == RC_DRIVER_IR_RAW". Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
