Subject: scsi: core: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e39a97353e5378eb46bf01679799c5704d397f32;p=linux.git

scsi: core: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()

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")
