From 8d2c9d25b725a699479d388da7e116d1d2bc0ea1 Mon Sep 17 00:00:00 2001 From: Jason Yan Date: Wed, 14 Dec 2022 21:38:06 +0800 Subject: [PATCH] scsi: libsas: Remove useless dev_list delete in sas_ex_discover_end_dev() The domain device 'child' is allocated in sas_ex_discover_end_dev() and used to be added to the dev_list in this function. After the following two fixes the device is added to the disco_list instead. As a result, the list_del() and locking left behind is now redundant. Fixes: 87c8331fcf72 ("[SCSI] libsas: prevent domain rediscovery competing with ata error handling") Fixes: 92625f9bff38 ("[SCSI] libsas: restore scan order") Cc: John Garry Signed-off-by: Jason Yan Reviewed-by: John Garry Signed-off-by: Martin K.
