    Subject[PATCH 4.14 063/117] usb-storage: Add unusual_devs entry for JMicron JMS566
    Date
    From: Alan Stern <stern@rowland.harvard.edu>

    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.
