Subject[PATCH v6 4/8] scsi: mvsas: use sas_find_attached_phy_id() instead of open coded
Date
The attached phy finding is open coded. Now we can replace it with
sas_find_attached_phy_id(). To keep consistent, the return value of
mvs_dev_found_notify() is also changed to -ENODEV after calling
sas_find_attathed_phy_id() failed.
