Subject: PM: sleep: core: Switch back to async_schedule_dev()
From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>
commit 09beebd8f93b3c8bf894e342f0a203a5c612478c upstream.
Commit 8b9ec6b73277 ("PM core: Use new async_schedule_dev command")
introduced a new function for better performance.
However commit f2a424f6c613 ("PM / core: Introduce dpm_async_fn()
helper") went back to the non-optimized version, async_schedule().
So switch back to the sync_schedule_dev() to improve performance
Fixes: f2a424f6c613 ("PM / core: Introduce dpm_async_fn() helper")
