Okay, looking closer to the current state of affairs, the change
does not fix anything actually. OTOH it's correct semantically and
allows to do any further development in charlcd_alloc(), if any.

That said, if Geert is okay with it, I would like to apply but without
Fixes/Cc: stable@ tags.

P.S.
The very similar needs to be applied to panel.c, but I already have
a patch for that locally, thanks to this thread.
