The newly introduced ab8500 external regulator driver causes an unexpected quirk when used with the Snowball low-cost development board. When the 3 ab8500 external regulators are registered, the ones which can be freed, are. Unfortunately, on Snowball one of them is connected to the MMC power line. Once freed, this turns off the MMC device. External regulators are not used on Snowball, so it's pointless registering them in the first place.
These two patches ensure external regulators aren't registered on Snowball or any other platforms which do not require them. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
