Hoisted the changelog above --- where it belongs in drm land,
amended with
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/203
and pushed the patch to dinq.
Thanks, and sorry for the horrendous latency.
PS. This will cause some headache for Uma's lspcon HDR stuff, but
so be it.

[Intel-gfx] [PATCH v6] drm/i915: Init lspcon after HPD in intel_dp_detect()
On HP 800 G4 DM, if HDMI cable isn't plugged before boot, the HDMI port
becomes useless and never responds to cable hotplugging:
[3.031904] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[3.031945] [drm:intel_ddi_init [i915]] *ERROR* LSPCON init failed on port D
Seems like the lspcon chip on the system only gets powered after the
cable is plugged.
Consilidate lspcon_init() into lspcon_resume() to dynamically init
lspcon chip, and make HDMI port work.

v6:
- Rebase on latest for-linux-next.
v5:
- Consolidate lspcon_resume() with lspcon_init().
- Move more logic into lspcon code.
v4:
- Trust VBT in intel_infoframe_init().
- Init lspcon in intel_dp_detect().
v3:
- Make sure it's handled under long HPD case.
