From 79e3b4c7dd1c54be4fdc77de9ba168bfa4e75567 Mon Sep 17 00:00:00 2001 From: lizhe Date: Tue, 7 Dec 2021 01:50:29 -0800 Subject: mmc: core: Remove redundant driver match function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches, see 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.
