The FIXME was there for LSPCON and shouldn't have been removed.
No one has yet figured out how to do this.

intel_ddi_post_disable_dp()->intel_dp_set_infoframes() will be executed for LSPCON, or am I missing something?

LSPCON generates its own infoframes, so turning off the video DIP does
diddly squat.

It would not be the lspcon job to do so when DP -> lspcon video is off?
Anyways will be sending the revert in a few minutes, please review that if we really need this fixme back.
