The DRM panel core already keeps track of if the panel is already
prepared so do not reimplement this.

It does? Can you please point to where/when the DRM panel core keeps
track of this? I know I've posted a patch for this at:

https://lore.kernel.org/r/20230607144931.v2.2.I59b417d4c29151cc2eff053369ec4822b606f375@changeid

...but I haven't landed it because I'm still trying to get consensus
on the rest of the series and a later patch in the series depends on
it.

If you have some evidence that my patch isn't needed, can you please
point at it in the commit message? I would say at least that someone
else seemed to agree that the core wasn't checking this [1], though I
guess it's possible that person was running old code or was just as
confused as I was.
