6.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx> commit f9eeb6bb13fb5d7af1ea5b74a10b1f8ead962540 upstream. The pplcllpl/u can be used to save the Link Connection Linear Link Position register value to be used for compensation of the LLP register value in case the counter is not reset (after pause/resume or stop/start without closing the stream). The LLP can be used along with PPHCLDP to calculate delay caused by the DSP processing for HDA links.
