Two small nits - otherwise looks good.
Reviewed-by: Sam Ravnborg <[email protected]>
I can fix while applying or you can send a new revision,
but I cannot apply until drm-misc-next have seen a backmerge
due to dev_err_probe() usage.
Did you have commit rights yet?
If yes, then please apply yourself.

I recall we discussed this before for some other driver.
For a single panel it is not needed, but if you continue to be active
on other parts it makes sense.
I will apply v3 when drm-misc-next is backmeged unless you tell me

I think st7703, mantix and nwl all go in via drm-misc so it might make
sense. Thanks for the suggestion!
