--- Comment #16 from Takashi Iwai <tiwai at suse.de> ---
Well, this is a sort of chicken-and-egg problem.  For probing the HDMI codec,
i915 binding is needed, yes.  But, for knowing whether it's a HDMI codec or
not, we need to probe the codec at first.  Thus the driver needs the i915
binding *before* probing the codec.  Yet, i915 binding can't be done when the
system has no i915 graphics...

We may look for Intel VGA PCI entries, and enable i915 binding only when found.
 This would work in most cases, but not in 100%.  User may still build / use a
system without graphics (e.g. booting with nomodeset option).
