Subject: [PATCH v2 3/5] dmaengine: imx-sdma: remove usless lock
Date: Fri, 8 Jun 2018 21:44:48 +0800 [thread overview]
Message-ID: <1528465490-19684-4-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1528465490-19684-1-git-send-email-yibin.gong@nxp.com>
No need anymore for 'lock' now since virtual dma will provide
the common lock instead.
