From a45309a37a09546993216a304f40315e74bbfb26 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 12 Jun 2024 15:12:03 +0300 Subject: [PATCH] ASoC: SOF: sof-audio: Skip unprepare for in-use widgets on error rollback [ Upstream commit 6f2a43e3d14f6e31a3b041a1043195d02c54d615 ] If the ipc_prepare() callback fails for a module instance, on error rewind we must skip the ipc_unprepare() call for ones that has positive use count. The positive use count means that the module instance is in active use, it cannot be unprepared. The issue affects capture direction paths with branches (single dai with multiple PCMs), the affected widgets are in the shared part of the paths.
