regression: GDM fails to display anything since c315fbfa ("drm/i915: Enable 10bpc + CCS on TGL+")

lspci -nn | grep VGA: 00:02.0 VGA compatible controller [0300]: Intel Corporation TigerLake-LP GT2 [Iris Xe Graphics] [8086:9a49] (rev 01)

With Linus' tree at commit aaf20f870da0 ("Merge tag 'rpmsg-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux"), GDM displays nothing. Its log contains:

     Failed to ensure KMS FB ID on /dev/dri/card1: drmModeAddFB2WithModifiers failed: Invalid argument
     meta_frame_native_release: assertion '!frame_native->kms_update' failed

Bisect has show commit c315fbfa ("drm/i915: Enable 10bpc + CCS on TGL+") is the first bad commit. Reverting 7c35015f ("drm/i915: Enable fp16 + CCS on TGL+") and that commit apparently fixes the issue.

The monitor is the laptop screen connected via eDP:

eDP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
   1920x1080     59.96*+
