Subject[PATCH 4.9 06/16] USB: storage: add quirk for SMI SM3350
Date
4.9-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.
