For me it also works if HDMI is not disabled.
So IMHO this comment is misleading.

HDMI disabled comment part but seems like that's not critical

[David Shah]

In any case the HDMI bug has reappeared while testing 5.9-rc1, although
I can get the display to work by doing 'modprobe omapdrm' even if HDMI
is enabled (as before it loads automatically if HDMI is disabled).
