Hi Dong,

You wouldn't believe it, but just 5 mins earlier i found the mail
chain you sent to me. I got this fix of moving claim_host below remove
and it worked for me too. But i faced another issue with the patch when
i suspend/resume again and again in a loop. It might or might not be
related to this patch.

But i don't see this work getting pushed into Linux.
What is the current state at your SoC? Are you keeping this issue open as
"Don't suspend with MMC card mounted"

Or you are working with this fix?

Thanks for the mail.
