From e13c3c081845b51e8ba71a90e91c52679cfdbf89 Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Thu, 17 Nov 2016 16:40:37 +0900 Subject: [PATCH] mmc: dw_mmc: call the dw_mci_prep_stop_abort() by default stop_cmdr should be set to values relevant to stop command. It migth be assigned to values whatever there is mrq->stop or not. Then it doesn't need to use dw_mci_prepare_command(). It's enough to use the prep_stop_abort for preparing stop command.
