<pre>Nothing obvious in the logs. The one change is that we now set the infoframe
for the LSPCON chip.
Can you test with latest drm-tip branch to make sure we haven't fixed this in
the meantime?
git://anongit.freedesktop.org/drm-tip drm-tip
To rule out the infoframe we could try something like this:
diff --git a/drivers/gpu/drm/i915/intel_lspcon.c
b/drivers/gpu/drm/i915/intel_lspcon.c
index 8d202b13e24f..1eac926c0821 100644
