4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Thumshirn <jthumshirn@xxxxxxx>
commit 835831c57e9b0cccc24e96a812542875471d75b5 upstream.
Use scsi_is_sas_rphy() instead of is_sas_attached() to decide whether we
should obtain the SAS address from a scsi device or not. This will
prevent us from tripping on the BUG_ON() in sas_sdev_to_rdev() if the
rphy isn't attached to the SAS transport class, like it is with hpsa's
logical devices.
Fixes: 3f8d6f2a0 ('ses: fix discovery of SATA devices in SAS enclosures')
