Subject[PATCH 5.10 20/70] ASoC: meson: Fix event generation for G12A tohdmi mux
Date
From: Mark Brown <broonie@kernel.org>

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.
