ASoC: meson: g12a-toacodec: Fix event generation
[ Upstream commit 172c88244b5f2d3375403ebb504d407be0fded59 ]
When a control changes value the return value from _put() should be 1 so
we get events generated to userspace notifying applications of the change.
We are checking if there has been a change and exiting early if not but we
are not providing the correct return value in the latter case, fix this.
