[52/70] mmc: sdhci-esdhc-imx: SDHCI_CARD_PRESENT does not get

[Greg KH]

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------
 cleared

From: Shawn Guo <shawn.guo@xxxxxxxxxx>

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.
