[PATCH 4.9 109/130] scsi: ses: Fix SAS device detection in enclosure

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ewan D. Milne <emilne@xxxxxxxxxx>

commit 9373eba6cfae48911b977d14323032cd5d161aae upstream.

The call to scsi_is_sas_rphy() needs to be made on the SAS end_device,
not on the SCSI device.

Fixes: 835831c57e9b ("ses: use scsi_is_sas_rphy instead of is_sas_attached")
