Subject: [PATCH 3.16 185/370] usb: storage: unusual_uas: Add JMicron
 JMS56x to unusual device

3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Oliver Neukum <oneukum@...e.com>

commit 674aea07e38200ea6f31ff6d5f200f0cf6cdb325 upstream.

This device gives the following error on detection.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring

The same error is not seen when it is added to unusual_device
list with US_FL_NO_REPORT_OPCODES passed.
