Revert "mmc: core: Convert mmc_driver to device_driver"
This reverts commit 6685ac62b2f0 ("mmc: core: Convert mmc_driver to device_driver") The reverted commit went too far in simplifing the device driver parts for mmc. Let's restore the old mmc_driver to enable driver core to sooner or later to remove the ->probe(), ->remove() and ->shutdown() callbacks from the struct device_driver. Note that, the old ->suspend|resume() callbacks in the struct mmc_driver don't need to be restored, since the mmc block layer has converted to the modern system PM ops. Fixes: 6685ac62b2f0 ("mmc: core: Convert mmc_driver to device_driver") Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Jaehoon Chung <jh80.chung@samsung.com>
