commit 94f9c8c3c404ee1f7aaff81ad4f24aec4e34a78b upstream.
Cyril Roelandt reports that his JMicron JMS566 USB-SATA bridge fails to handle WRITE commands with the FUA bit set, even though it claims to support FUA. (Oddly enough, a later version of the same bridge, version 2.03 as opposed to 1.14, doesn't claim to support FUA. Also oddly, the bridge _does_ support FUA when using the UAS transport instead of the Bulk-Only transport -- but this device was blacklisted for uas in commit bc3bdb12bbb3 ("usb-storage: Disable UAS on JMicron SATA enclosure") for apparently unrelated reasons.)
This patch adds a usb-storage unusual_devs entry with the BROKEN_FUA flag. This allows the bridge to work properly with usb-storage.
