Yes, i've seen similar with power management bugs for the MDIO
driver. But you get a cascade of failures, lots of warnings and error
prints, it is clear something bad has happened, and the switch is in
an inconsistent state. So having one more debug print which is also
inconsistent does no really harm.

Anyway, this whole conversation has taken more effort than just making
this simple change to remove a few lines of code. So lets drop it and
move on.
