Subject: [PATCH AUTOSEL 4.9 2/2] usb-storage: Disable UAS on JMicron SATA enclosure

From: Laura Abbott <labbott@...oraproject.org>

[ Upstream commit bc3bdb12bbb3492067c8719011576370e959a2e6 ]

Steve Ellis reported incorrect block sizes and alignement
offsets with a SATA enclosure. Adding a quirk to disable
UAS fixes the problems.
