6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@xxxxxxx> commit 245f3b149e6cc3ac6ee612cdb7042263bfc9e73c upstream. Update watermark will be done inside the hwfifo_set_watermark callback just after the update_scan_mode. It is useless to do it here.
