[PATCH v2 20/22] bluetooth: Let suspend-on-idle request audio in headset

[mikel.astiz.oss@xxxxxxxxx (Mikel Astiz)]

From: Mikel Astiz <mikel.astiz@xxxxxxxxxxxx>

When PA is doing gateway role, let module-suspend-on-idle resume the
audio stream automatically. This will work until the user (or the remote
side, which we also consider user-initiated) suspend the stream
manually.
