| Subject: [PATCH 1806/1808] mmc: tmio: Fix tuning flow |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| If the return value of mmc_send_tuning() is error other than -EILSEQ, |
| the tuning fails and process goes out of for_loop. The correct |
| processing is to judge their TAP as not good (NG) and continue. |
