[PATCH 5.4 026/260] dmaengine: imx-sdma: remove duplicated sdma_load_context

From: Greg Kroah-Hartman
Date: Mon Sep 20 2021 - 14:06:50 EST


From: Robin Gong <yibin.gong@xxxxxxx>

commit e555a03b112838883fdd8185d613c35d043732f2 upstream.

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")
