Subject: [PATCH] mmc: sunxi-mmc: Ensure host is suspended during system sleep
Date: Tue, 12 Jan 2021 23:24:21 -0600 [thread overview]
Message-ID: <20210113052421.36553-1-samuel@sholland.org> (raw)
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.
