| Subject: ASoC: max98090: Generate notifications on changes for custom control |
| |
| From: Mark Brown <broonie@kernel.org> |
| |
| [ 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. |
