Though this has nothing specific with this patch, an interesting point.

git grep -w opp . showed drivers/tty/n_tty.c,
drivers/sbus/char/openprom.c and arch/powerpc/kvm/mpic.c using
variables named opp to mean what ever they had in context. rest(around
40 odd files) seem to use opp as in Documentation/power/opp.txt..

We could go with a pm_ prefix or even dev_pm_opp_ prefix to be more
specific, though I prefer just pm_. If Rafael and others are ok, I can
post a series out.
