    Subject[PATCH 4.14 085/118] uas: ignore UAS for Norelsys NS1068(X) chips
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Icenowy Zheng <icenowy@aosc.io>

    commit 928afc85270753657b5543e052cc270c279a3fe9 upstream.

    The UAS mode of Norelsys NS1068(X) is reported to fail to work on
    several platforms with the following error message:

    xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
    xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001

    And when trying to mount a partition on the disk the disk will
    disconnect from the USB controller, then after re-connecting the device
    will be offlined and not working at all.

    Falling back to USB mass storage can solve this problem, so ignore UAS
    function of this chip.
