From 31606a73baa35acdae6ab95ff5d3928e2d8b4cb0 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 20 Apr 2022 20:34:54 +0100 Subject: [PATCH] ASoC: max98090: Generate notifications on changes for custom control [ Upstream commit 13fcf676d9e102594effc686d98521ff5c90b925 ] The max98090 driver has some custom controls which share a put() function which returns 0 unconditionally, meaning that events are not generated when the value changes. Fix that.
