DESCRIPTION

Helper for GPUs whose power state is controlled by the driver's runtime pm. When the driver decides to power up or down, it notifies vga_switcheroo thereof using this helper so that it can (a) power the audio device on the GPU up or down, and (b) update its internal power state representation for the device.
