In the case of MMC the MMC guys told us that this supply was entirely
optional for MMC operation, it wasn't an essential supply for the MMC
device to run it just enabled more features. For supplies like that
it's OK for the regulator to fail, the driver should just not do
whatever things are enabled by having that supply.
