Could, but you'll note a later patch eliminates both pp_status and
pp_control local variables, so I didn't bother to clean this up when
refactoring.

Yeah, probably not necessary. I just added checks everywhere I could
think of to try and figure out where power was not being applied when
needed.

Should I bother to include this patch in the series at all? It's purely
for diagnostics to make sure the panel is powered during all aux channel
transactions.
