[PATCH v2 3/3] mmc: sdhci: properly check card present state when quirk NO_CARD_NO_RESET is set

From: Ivan T. Ivanov
Date: Mon Jul 06 2015 - 08:16:44 EST


Controller could have both NO_CARD_NO_RESET and BROKEN_CARD_DETECTION
quirks set. Use sdhci_do_get_cd() when applying NO_CARD_NO_RESET, which
properly check for BROKEN_CARD_DETECTION quirk.
