The attribute is only meaningful for vga clients. It is never used for audio clients. The function vga_switcheroo_register_audio_client() misuses this attribute to store whether the audio device is fully initialized. Most likely there was a misunderstanding about the meaning of "active" when this was added. Set the active attribute to false for audio clients. Remove the active parameter from vga_switcheroo_register_audio_client() and its sole caller, hda_intel.c:register_vga_switcheroo(). vga_switcheroo_register_audio_client() was introduced by 3e9e63dbd374 ("vga_switcheroo: Add the support for audio clients"). Its use in hda_intel.c was introduced by a82d51ed24bb ("ALSA: hda - Support VGA-switcheroo"). v1.1: The changes above imply that in find_active_client() the call to client_is_vga() is now superfluous. Drop it.
