| Subject: [PATCH 120/286] 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. |
