From c64e77490b7e5d9dec738850f18878edb07e0f13 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Wed, 29 Apr 2026 11:53:15 +0100 Subject: [PATCH] ASoC: cs35l56: Fix hibernate write in runtime resume error path The error path of cs35l56_runtime_resume_common() should only write the hibernation sequence if can_hibernate is true. Something has already gone badly wrong if we ever reach the error path. But triggering hibernate on hardware that does not support it is likely to make the situation unrecoverable without a full reboot because there might not be any hardware signal to exit hibernate.
