ASoC: max98090: Generate notifications on changes for custom control
[ Upstream commit 13fcf676d9e102594effc686d98521ff5c90b925 ]
The max98090 driver has some custom controls which share a put() function
which returns 0 unconditionally, meaning that events are not generated
when the value changes. Fix that.
