From 61c45cece50bad12a32fe4611d98e76e2bb397a2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 21 Apr 2022 13:38:03 +0100 Subject: [PATCH] ASoC: meson: Fix event generation for G12A tohdmi mux commit 12131008fc13ff7f7690d170b7a8f72d24fd7d1e upstream. The G12A tohdmi 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.
