mmc: sdhci-esdhc-imx: SDHCI_CARD_PRESENT does not get cleared
commit 803862a6f7de4939e0a557214e5e4b37e36f87ff upstream. The function esdhc_readl_le intends to clear bit SDHCI_CARD_PRESENT, when the card detect gpio tells there is no card. But it does not clear the bit actually. The patch gives a fix on that.
