Date: Sun, 19 Mar 2023 12:35:18 +0800 From: Lizhe <sensor1010@....com> To: yangyingliang@...wei.com, michael.chritie@...cle.com Cc: linux-scsi@...r.kernel.org, target-devel@...r.kernel.org, linux-kernel@...r.kernel.org, Lizhe <sensor1010@....com> Subject: [PATCH] scsi:target:tcm_loop: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 bus's match function that always returned 1 and so implements the same behaviour as when there is no match function.
