The PM_RESTORE_PREPARE is not handled now in mmc_pm_notify(), as result mmc_rescan() could be scheduled and executed at late hibernation restore stages when MMC device is suspended already - which, in turn, will lead to system crash on TI dra7-evm board: WARNING: CPU: 0 PID: 3188 at drivers/bus/omap_l3_noc.c:148 l3_interrupt_handler+0x258/0x374() 44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4_PER1_P3 (Idle): Data Access in User mode during Functional access Hence, add missed PM_RESTORE_PREPARE PM event in mmc_pm_notify().
