Subject: scsi_transport_sas: always pass 0 error to blk_end_request_all
X-Git-Tag: v5.15~11401^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d188b90c48e418e102a1f42872b13dfe386ab6a7;p=platform%2Fkernel%2Flinux-starfive.git

scsi_transport_sas: always pass 0 error to blk_end_request_all

The SAS transport queues are only used by bsg, and bsg always looks at
the scsi_request results and never add the error passed in the end_io
callback.
