Subject: [PATCH] ASoC: Intel: Skylake: Notify BE about stream update
|
|
|
|
In order to implement virtualization, FE driver should receive
|
|
notifications about stream state changes. This patch notifies
|
|
BE service, which should forward this information to FE driver.
|
|
|
|
If virtualization is not enabled, notification function will be
|
|
removed during compilation.
