s390/vfio-ap: remove redundant driver match function
If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches, see driver_match_device(). Drop the matrix bus's match function that always returned 1 and so implements the same behaviour as when there is no match function Signed-off-by: Lizhe <sensor1010@163.com> Reviewed-by: Tony Krowiak <akrowiak@linux.ibm.com> Link: https://lore.kernel.org/r/20230319041941.259830-1-sensor1010@163.com Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
