Subject: mmc: fix rmmod race for hosts using card-detection polling
From: Guennadi Liakhovetski <[email protected]>
commit d9bcbf343ec63e1104b5276195888ee06b4d086f upstream.
MMC hosts that poll for card detection by defining the MMC_CAP_NEEDS_POLL
flag have a race on rmmod, where the delayed work is cancelled without
waiting for completed polling. To prevent this a _sync version of the work
cancellation has to be used.
