From fabb3a43ada899e6ed248c3dee62348114831227 Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Fri, 27 Mar 2020 13:08:01 +0900 Subject: mmc: sdhci: not return error when SDMA is not supported If Host controller doesn't support SDMA, it doesn't need to return error. Because it can be worked with PIO mode.
