Don't dereference mode which was just NULL checked.

The mantix panel needs two reset lines (RESX and TP_RSTN) deasserted to
output an image. Only deasserting RESX is not enough and the display
will stay blank. Deassert in prepare() and assert in unprepare() to keep
device held in reset when off.

We need to reset both for the panel to show an image.

All applied to drm-misc-next and pushed out.
And then I remembered you had commit right - sigh.

Thanks! Is there any special care needed to get that into 5.10? The
driver landed there in 72967d5616d3f0c714f8eb6c4e258179a9031c45.

As the patches was applied to drm-misc-next the easiet path would
be to cherry-pick them and apply to drm-misc-fixes.
dim has cherry-pick support - try to use it rahter than doing it by
hand.
When you apply to drm-misc-fixes include a Fixes: tag so the tooling
will pick the patches automagically.
In hindsight the patches should have carried a Fixes: tag from a start
and should have been applied to drm-misc-fixes from a start too.
I have done something like above once or twice but anyway reach out if
you have questions. Or ask at #dri-devel.

Does that require any further ACKs or just cherry-pick and push out?

Will do. It was unfortunate that the initial ones didn't get them but
i think the drm merge happened while v2 was out on the list. I'll try
add that relevant information to the cover letter in the future.

To the best of my knowledge just cherry-pick, test and push out.
