Probably by looking closely at the implementation of the PM callouts
for the driver, but I couldn't find a pattern that would be easy to
recognize. Maybe I didn't look close enough ;-)

I concur that removing the check would be a better approach if it's
clear that it's just done "out of habit".

Actually, the real problem is to find the drivers that need to have
the check in, add/fix it for them, and remove it for all others.

Unfortunately, all I'm currently able to do is finding the parts that
are inconsistent.
