From: Allen-KH Cheng <Allen-KH.Cheng@xxxxxxxxxxxx> In SOF OF device, pm_runtime_put_autosuspend() is not matching any pm_runtime_get_sync(). This is imbalanced for PM runtime. Also, for consistency we call pm_runtime_mark_last_busy() before enabling PM runtime. 1. Remove pm_runtime_put_autosuspend() in probe_complete 2. Reorder PM runtime calls int probe_complete Signed-off-by: Allen-KH Cheng <Allen-KH.Cheng@xxxxxxxxxxxx> Reviewed-by: Daniel Baluta <daniel.baluta@xxxxxxx> Reviewed-by: Paul Olaru <paul.olaru@xxxxxxxxxxx> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> --- sound/soc/sof/sof-of-dev.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/sound/soc/sof/sof-of-dev.c b/sound/soc/sof/sof-of-dev.c index 412cbb824b84..b0089698eecb 100644 --- a/sound/soc/sof/sof-of-dev.c +++ b/sound/soc/sof/sof-of-dev.c @@ -74,11 +74,9 @@ static void sof_of_probe_complete(struct device *dev) /* allow runtime_pm */ pm_runtime_set_autosuspend_delay(dev, SND_SOF_SUSPEND_DELAY_MS); pm_runtime_use_autosuspend(dev); + pm_runtime_mark_last_busy(dev); pm_runtime_set_active(dev); pm_runtime_enable(dev); - - pm_runtime_mark_last_busy(dev); - pm_runtime_put_autosuspend(dev); } static int sof_of_probe(struct platform_device *pdev) -- 2.27.0
