Subject: [PATCH 4/9] qla2xxx: don't break the bsg-lib abstractions
Date: Tue, 3 Oct 2017 12:48:40 +0200 [thread overview]
Message-ID: <20171003104845.10417-5-hch@lst.de> (raw)
In-Reply-To: <20171003104845.10417-1-hch@lst.de>
Always use bsg_job->reply instead of scsi_req(bsg_job->req)->sense), as
they always point to the same memory.
Never set scsi_req(bsg_job->req)->result and we'll set that value through
bsg_job_done.
