Register a component to be used to interface with the snd_hda_intel driver. This is meant to replace the same interface that is currently based on module symbol lookup. v2: - change roles between the hda and i915 components (Daniel) - add the implementation to a new file (Jani) - use better namespacing (Jani) v3: - move the implementation to intel_audio.c (Daniel) - rename display_component to audio_component (Daniel) - add kerneldoc (Daniel) v4: - run forgotten git rm i915_component.c (Jani) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
