From eb7c00e1461124ad0e85f1a9a3954d7164809c13 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 14 Mar 2017 11:09:19 +0100 Subject: [PATCH] mmc: host: tmio: fill in response from auto cmd12 After we received the dataend interrupt, R1 response register carries the value from the automatically generated stop command. Report that info back to the MMC block layer, so we will be notified in case of e.g. ECC errors which happened during the last transfer.
