[PATCH v16 04/12] dmaengine: imx-sdma: remove duplicated sdma_load_context

From: Robin Gong <hidden>
Date: 2021-07-14 02:04:58
Also in: dmaengine, linux-arm-kernel, linux-devicetree, lkml
Subsystem: dma generic offload engine subsystem, the rest · Maintainers: Vinod Koul, Linus Torvalds

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: <redacted>
