[PATCH v3 2/3] ses: use scsi_is_sas_rphy instead of is_sas_attached

Show all headers | View raw

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.
