Subject: [PATCH 4.14 10/27] USB: storage: dont insert sane sense for SPC3+ when bad sense specified
Date: Tue, 15 Jan 2019 17:35:59 +0100 [thread overview]
Message-ID: <20190115154901.833132270@linuxfoundation.org> (raw)
In-Reply-To: <20190115154901.189747728@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Icenowy Zheng <icenowy@aosc.io>
commit c5603d2fdb424849360fe7e3f8c1befc97571b8c upstream.
Currently the code will set US_FL_SANE_SENSE flag unconditionally if
device claims SPC3+, however we should allow US_FL_BAD_SENSE flag to
prevent this behavior, because SMI SM3350 UFS-USB bridge controller,
which claims SPC4, will show strange behavior with 96-byte sense
(put the chip into a wrong state that cannot read/write anything).
Check the presence of US_FL_BAD_SENSE when assuming US_FL_SANE_SENSE on
SPC4+ devices.
