Subject: [PATCH v3 12/17] dmaengine: bcm-sba-raid: Pre-ack async tx descriptor
Date: Tue, 22 Aug 2017 15:27:01 +0530 [thread overview]
Message-ID: <1503395827-19428-13-git-send-email-anup.patel@broadcom.com> (raw)
In-Reply-To: <1503395827-19428-1-git-send-email-anup.patel@broadcom.com>
We should pre-ack async tx descriptor at time of
allocating sba_request (just like other RAID drivers).
