From b640e8a4bd24e17ce24a064d704aba14831651a8 Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Fri, 28 May 2021 17:43:30 +0300 Subject: [PATCH] ASoC: SOF: reset enabled_cores state at suspend The recent changes to use common code to power up/down DSP cores also removed the reset of the core state at suspend. It turns out this is still needed. When the firmware state is reset to SOF_FW_BOOT_NOT_STARTED, also enabled_cores should be reset, and existing DSP drivers depend on this.
