Subject: Re: [PATCH 4.14 199/496] scsi: core: return BLK_STS_OK for DID_OK in
 __scsi_error_from_host_byte()

question:
drop because of upstream's

cbe095e2b584 ("Revert "scsi: core: return BLK_STS_OK for DID_OK in 
__scsi_error_from_host_byte()"")
Fixes: e39a97353e53 ("scsi: core: return BLK_STS_OK for DID_OK in
__scsi_error_from_host_byte()")

as in stable-queue's

c40541008b93 ("drop a scsi patch from 4.14")

?
