Subject: scsi: libsas: Remove useless dev_list delete in
sas_ex_discover_end_dev()
Git-commit: 8d2c9d25b725a699479d388da7e116d1d2bc0ea1
Patch-mainline: v6.3-rc1
References: git-fixes
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")
