Subject: scsi: ses: Fix SAS device detection in enclosure
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a07a122ad2a2e03209155fe907bf8b1e6ae4c915;p=linux-beck.git

scsi: ses: Fix SAS device detection in enclosure

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")
