From f2a58481a5051704390c2d7653b07ab3d97782da Mon Sep 17 00:00:00 2001 From: Stefan Binding Date: Fri, 21 Jul 2023 16:18:10 +0100 Subject: [PATCH] ALSA: hda: cs35l41: Ensure we pass up any errors during system suspend. There are several steps required to put the system into system suspend. Some of these steps may fail, so the driver should pass up the errors if they occur.
