Yes, I noticed that I had no LCD output on an imx6ull-evk board and
after selecting CONFIG_FB it works again.

For the entire series:

this was caused by:

f611b1e7624c ("drm: Avoid circular dependencies for CONFIG_FB")

Thanks, Stefan.

Marcel, I think you could resend this one with the Fixes tag and
hopefully it could be applied as a fix for 5.14-rc.

We can consider it as a regression fix, because it restores display
support on many i.MX boards on 5.14-rc.

Thanks
