Subject: [PATCH v16 04/12] dmaengine: imx-sdma: remove duplicated sdma_load_context
Date: Wed, 14 Jul 2021 18:20:44 +0800 [thread overview]
Message-ID: <1626258052-22198-5-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1626258052-22198-1-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().
Fixes: ad0d92d7ba6a ("dmaengine: imx-sdma: refine to load context only once")
Cc: <stable@vger.kernel.org>
