| Subject: [PATCH] mmc: sdhci: do not enable card detect interrupt for gpio cd |
| type |
| |
| commit e65bb38824711559844ba932132f417bc5a355e2 upstream. |
| |
| Except SDHCI_QUIRK_BROKEN_CARD_DETECTION and MMC_CAP_NONREMOVABLE, |
| we also do not need to handle controller native card detect interrupt |
| for gpio cd type. |
| If we wrong enabled the card detect interrupt for gpio case, it will |
| cause a lot of unexpected card detect interrupts during data transfer |
| which should not happen. |
