Subject: [PATCH v1] vfio/mdev: Remove redundant driver match function
Date: Sun, 19 Mar 2023 13:01:30 +0800 [thread overview]
Message-ID: <20230319050130.360515-1-sensor1010@163.com> (raw)
If there is no driver match function, the driver core assumes that each
candidate pair (driver, device) matches, see driver_match_device().
Drop the bus's match function that always returned 1 and so
implements the same behaviour as when there is no match function.
