Can Guo ce4f62f9dd scsi: ufs: core: Narrow down fast path in system suspend path ... If spm_lvl is set to 0 or 1, when system suspend kicks start and HBA is runtime active, system suspend may just bail without doing anything (the fast path), leaving other contexts still running, e.g., clock gating and clock scaling. When system resume kicks start, concurrency can happen between ufshcd_resume() and these contexts, leading to various stability issues. Add a check against HBA's runtime state and allowing fast path only if HBA is runtime suspended, otherwise let system suspend go ahead call ufshcd_suspend(). This will guarantee that these contexts are stopped by either runtime suspend or system suspend.
