Subject: [RESEND v6  04/13] dmaengine: imx-sdma: remove dupilicated sdma_load_context
Date: Tue, 10 Mar 2020 19:31:53 +0800	[thread overview]
Message-ID: <1583839922-22699-5-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1583839922-22699-1-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().
