Subject: [PATCH v2 0/2] USB Storage quirk for SMI SM3350

SMI SM3350 UFS-USB bridge controller cannot handle REQUEST SENSE command
with long sense (96-bytes) well, and will even trap the controller into
a state that refuses to do read/write command.

Currently Linux uncondintionally set US_FL_SANE_SENSE for devices
claiming SPC3+, which makes simply add US_FL_BAD_SENSE for SM3350 fail
(as it claims SPC4).

Fix this conflicting quirk issue, and add the quirk for SM3350.

Icenowy Zheng (2):
  USB: storage: don't insert sane sense for SPC3+ when bad sense
    specified
  USB: storage: add quirk for SMI SM3350
