From 882f4adac9a8411ba9993810132add18896b82c1 Mon Sep 17 00:00:00 2001 From: Lizhe Date: Sun, 19 Mar 2023 12:35:18 +0800 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(). pseudo_lld_bus_match() always returns 1 and is therefore equivalent to not registering a match function. Remove it.
