From: Robin Gong <yibin.gong@nxp.com> stable inclusion from stable-5.10.67 commit bcbc44e42dc676fa63c111617533d15c4cf444de bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit e555a03b112838883fdd8185d613c35d043732f2 upstream. Since sdma_transfer_init() will do sdma_load_context before any sdma transfer, no need once more in sdma_config_channel().
