From: Lizhe Date: Sun, 19 Mar 2023 04:27:32 +0000 (+0800) Subject: scsi: scsi_debug: Remove redundant driver match function X-Git-Tag: v6.4-rc1~133^2~28 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c45b3804292ba5f95b86a8866e2e2cac03fa0155;p=thirdparty%2Flinux.git scsi: scsi_debug: 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 pseudo_lld bus match function that always returned 1. This results in the same behaviour as when there is no match function.
