| |
From: Mark Brown <broonie@kernel.org>
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.
