Some drivers worked around this in various ways: esdhc-imx defines an IO accessor to fake the presence bit being true, s3c turns on polling (which stops the SDHCI driver from checking the bit) after a card's inserted. But none of this should be necessary; the real fix is to check whether we're using a GPIO and avoid relying on the presence bit if so, as this patch implements.
