From 9c0f5bbff146f09f449dd528addeabfb68aef997 Mon Sep 17 00:00:00 2001 From: Simon Trimmer Date: Thu, 14 May 2026 16:18:54 +0100 Subject: [PATCH] ASoC: cs35l56: Log SoundWire status updates only on changes The SoundWire slave update_status() callback can be invoked when the status has not changed. To prevent large amounts of log noise with debug enabled, log them only when the status changes. This also helps with understanding them, because they now log an actual change in state.
