    Subject[PATCH 4.19 16/50] USB: storage: add quirk for SMI SM3350
    Date
    4.19-stable review patch.  If anyone has any objections, please let me know.

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

    From: Icenowy Zheng <icenowy@aosc.io>

    commit 0a99cc4b8ee83885ab9f097a3737d1ab28455ac0 upstream.

    The SMI SM3350 USB-UFS bridge controller cannot handle long sense request
    correctly and will make the chip refuse to do read/write when requested
    long sense.

    Add a bad sense quirk for it.
