Subject: [PATCH 3/4] ASoC: meson: g12a-toacodec: Fix event generation

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.

Fixes: af2618a2eee8 ("ASoC: meson: g12a: add internal DAC glue driver")
