I rather wanted the infoframes bitmask to be truthful about which
packets we're sending out. But not quite sure why I included it in
this particular patch.

Yeah it's the same thing (apart from the g4x DIP enable thing). Maybe
I should remove has_hdmi_sink entirely and just rely on the null packet
bit instead...

That would the other option I suppose. Though I might like the idea
of dropping the bool for the bitmask a bit more perhaps.

Misplaced hunk? Assuming I'm reading this correctly, this will give you a
0. Not exactly sure what's going on here ... I guess I'm not following why
we care about TYPE_NULL, and why we have to reconstruct it here?
I thought TYPE_NULL is equivalent to state->has_hdmi_sink? Comment
(unfortunately not yet kerneldoc) even explains that ...
Maybe just nuke all the TYPE_NULL tracking here, perhaps with the g4x
(except for g4x itself, because it's shared there) decoder to also take
DIP_ENABLE into account for has_hdmi_sink.
Or update the comment in intel_crtc_state.
Otherwise lgtm, thought admittedly I did clean over the details a bit,
trusting CI and gcc to catch the small stuff :-)

[Intel-gfx] [PATCH 13/18] drm/i915: Precompute HDMI infoframes
From: Ville Syrjälä
Store the infoframes in the crtc state and precompute them in
.compute_config(). While precomputing we'll also fill out the
inforames.enable bitmask appropriately.
