Can Guo c72e79c0ad scsi: ufs: Recover HBA runtime PM error in error handler ... The current error handler can not recover HBA runtime PM error if ufshcd_suspend/resume has failed due to UFS errors, e.g. hibern8 enter/exit error or SSU cmd error. When this happens, error handler may fail performing a full reset and restore because error handler always assumes that power, IRQs and clocks are ready after pm_runtime_get_sync returns, but actually they are not if ufshcd_resume fails[1]. If ufschd_suspend/resume fails due to UFS errors, runtime PM framework saves the error value to dev.power.runtime_error. After that, HBA dev runtime suspend/resume would not be invoked anymore unless runtime_error is cleared[2]. In case of ufshcd_suspend/resume fails due to UFS errors, for scenario [1], error handler cannot assume anything of pm_runtime_get_sync, meaning error handler should explicitly turn ON powers, IRQs and clocks again. To get the HBA runtime PM work as regard for scenario [2], error handler can clear the runtime_error by calling pm_runtime_set_active() if full reset and restore succeeds. And, more important, if pm_runtime_set_active() returns no error, which means runtime_error has been cleared, we also need to resume those scsi devices under HBA in case any of them has failed to be resumed due to HBA runtime resume failure. This is to unblock blk_queue_enter in case there are bios waiting inside it.
