mmc: dw_mmc-rockchip: Just set default sample value for legacy mode
.set_ios() is called from .resume() as well. For SDIO device which sets keep-power-in-suspend, nothing should be changed after resuming, as well as sample tuning value, since this value is tuned already. So we should not overwrite it with the default value. Signed-off-by: Shawn Lin <> Link: Signed-off-by: Ulf Hansson <>
