From 33790d1f039114a829433b89fc55a0d781d38d62 Mon Sep 17 00:00:00 2001 From: Stefan Binding Date: Thu, 26 Oct 2023 16:05:56 +0100 Subject: ALSA: hda: cs35l41: Do not unload firmware before reset in system suspend Given the part is about to reset due to system suspend, and we are already in hibernate, there is no need to wake up the amp, just to get it ready to be reset. We just need to ensure cs_dsp is ready for reset by resetting the states.
