Subject: mmc: sdhci-esdhc-imx: SDHCI_CARD_PRESENT does not get
cleared
From: Shawn Guo <shawn....@linaro.org>
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.
