From 2e3a0d1bfa95b54333f7add3e50e288769373873 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 21 Apr 2022 13:38:01 +0100 Subject: ASoC: meson: Fix event generation for AUI ACODEC mux The AIU ACODEC 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.
