Ohad Ben-Cohen ed919b0125 mmc: sdio: fix runtime PM anomalies by introducing MMC_CAP_POWER_OFF_CARD ... Some board/card/host configurations are not capable of powering off the card after boot. To support such configurations, and to allow smoother transition to runtime PM behavior, MMC_CAP_POWER_OFF_CARD is added, so hosts need to explicitly indicate whether it's OK to power off their cards after boot. SDIO core will enable runtime PM for a card only if that cap is set. As a result, the card will be powered down after boot, and will only be powered up again when a driver is loaded (and then it's up to the driver to decide whether power will be kept or not). This will prevent sdio_bus_probe() failures with setups that do not support powering off the card.
