Patch looks fine, but shortlog (subject) and changelog should be more
clear. These should be written for people who are not as familiar
with the code. For example, seeing this shortlog in a git history
would not be helpful as the irst thing one would ask is "what OPP1
issue?"
How about something like this:
Subject: OMAP3: PM: do not allow OPP1 allow for VDD2
Since OPP1 is not a supported OPP for VDD2, do not allow it to be
changed using the sysfs interface.
