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.
