ldo1_reg in addition to being connected to the io lines is also connected to the card detect line. On card removal, omap_hsmmc driver does a regulator_disable causing card detect line to be pulled down. This raises a card insertion interrupt and once the MMC core detects there is no card inserted, it does a regulator disable which again raises a card insertion interrupt. This happens in a loop causing infinite MMC interrupts. Fix it by making ldo1_reg as always_on.
