6.6-stable review patch. If anyone has any objections, please let me know.

commit daf7795406bf307997366f694888bd317ae5b5fa upstream.
ufshcd_init() calls pm_runtime_get_sync() before it calls async_schedule(). ufshcd_async_scan() calls pm_runtime_put_sync() directly or indirectly from ufshcd_add_lus(). Simplify ufshcd_async_scan() by always calling pm_runtime_put_sync() from ufshcd_async_scan().
