    Subject[PATCH 4.14 199/496] scsi: core: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Hannes Reinecke <hare@suse.de>

    [ Upstream commit e39a97353e5378eb46bf01679799c5704d397f32 ]

    When converting __scsi_error_from_host_byte() to BLK_STS error codes the
    case DID_OK was forgotten, resulting in it always returning an error.

    Fixes: 2a842acab109 ("block: introduce new block status code type")
