Something like: drivers/mmc/core/bus: Remove redundant driver match function If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches. See function driver_match_device(). Drop the mmc bus's match function that always returned 1 and so implements the same behaviour as when there is no match function.
