From 7011cc9a2188135494b29b8199893089226b6aad Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 21 Apr 2022 13:38:02 +0100 Subject: [PATCH] ASoC: meson: Fix event generation for AUI CODEC mux commit fce49921a22262736cdc3cc74fa67915b75e9363 upstream. The AIU CODEC has a custom put() operation which returns 0 when the value of the mux changes, meaning that events are not generated for userspace. Change to return 1 in this case, the function returns early in the case where there is no change.
