From 592b179fa1492b53554a405924db0669c00548be Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Wed, 19 Feb 2020 16:22:40 +0800 Subject: [PATCH] mmc: sdhci: do not enable card detect interrupt for gpio cd type [ Upstream commit e65bb38824711559844ba932132f417bc5a355e2 ] 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.
