ASoC: meson: Fix event generation for G12A tohdmi mux

broonie · broonie · commit 12131008fc13 · 2022-04-21T14:41:55.000+01:00
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.
