[PATCH] mmc: sunxi-mmc: Ensure host is suspended during system sleep

From: Samuel Holland
Date: Wed Jan 13 2021 - 00:25:51 EST


If the device suspend process begins before the mmc host's autosuspend
timeout, the host will continue running during system sleep. Avoid
this by forcing runtime suspend during a global suspend transition.
