From: Dmitry Katsubo <dmitry.katsubo@xxxxxxxxx>

commit 9fa62b1a31c96715aef34f25000e882ed4ac4876 upstream.

The patch extends the family of SATA-to-USB JMicron adapters that need
FUA to be disabled and applies the same policy for uas driver.
See details in http://unix.stackexchange.com/questions/237204/
