commit 1d53864c3617f5235f891ca0fbe9347c4cd35d46 upstream.
Currently if device needs to do flush or BKOP operations, the device VCC
power is kept during runtime-suspend period.
However, if system suspend is happening while device is runtime-suspended,
such power may not be disabled successfully.
The reasons may be,
1. If current PM level is the same as SPM level, device will keep
runtime-suspended by ufshcd_system_suspend().
2. Flush recheck work may not be scheduled successfully during system
suspend period. If it can wake up the system, this is also not the
intention of the recheck work.
To fix this issue, simply runtime-resume the device if the flush is allowed
during runtime suspend period. Flush capability will be disabled while
leaving runtime suspend, and also not be allowed in system suspend period.
