Subject: [PATCH AUTOSEL 3.18 31/98] uas: disable UAS on Apricorn SATA dongles

From: "Darrick J. Wong" <darrick.wong@...cle.com>

[ Upstream commit 36d1ffdb210ec2d0d6a69e9f6466ae8727d34119 ]

The Apricorn SATA dongle will occasionally return "USBSUSBSUSB" in
response to SCSI commands when running in UAS mode.  Therefore,
disable UAS mode on this dongle.
