4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bart.vanass...@wdc.com>
commit cbe095e2b584623b882ebaf6c18e0b9077baa3f7 upstream.
The description of commit e39a97353e53 is wrong: it mentions that commit
2a842acab109 introduced a bug in __scsi_error_from_host_byte() although that
commit did not change the behavior of that function. Additionally, commit
e39a97353e53 introduced a bug: it causes commands that fail with
hostbyte=DID_OK and driverbyte=DRIVER_SENSE to be completed with
BLK_STS_OK. Hence revert that commit.
Fixes: e39a97353e53 ("scsi: core: return BLK_STS_OK for DID_OK in
__scsi_error_from_host_byte()")
