> Unify the show() and store() styles of attr,
What is the problem with current naming that you are facing ? What's
there to unify? Are there two types of names used here ?
If that is so, please explain them first as I am not able to
understand why you are making this change.

I don't see why we would need to make this change and what good it brings. I would have supported this if cpufreq itself had different names, but for this one, No.

I will let Rafael take a call on that.
