Subject: [PATCH v8 04/13] dmaengine: imx-sdma: remove duplicated sdma_load_context
Date: Thu, 21 May 2020 04:34:16 +0800 [thread overview]
Message-ID: <1590006865-20900-5-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1590006865-20900-1-git-send-email-yibin.gong@nxp.com>
Since sdma_transfer_init() will do sdma_load_context before any
sdma transfer, no need once more in sdma_config_channel().
Signed-off-by: Robin Gong <yibin.gong@nxp.com>
