Subject: [PATCH v10 04/12] dmaengine: imx-sdma: remove duplicated sdma_load_context
Date: Tue, 30 Jun 2020 21:31:08 +0800
Message-ID: <1593523876-22387-5-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1593523876-22387-1-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().
