See the commit message of patch 2, Mr. Robot. I don't think it's worth
adding checking code in the callers, and replacing the current null
pointer dereference with a BUG() is an improvement IMHO.
If anybody disagrees with this, please say so.
other option could be to use WARN_ON to make Mr. Robot happy and
then return first/last/default power well to make callers happy
