Hi,

Two cleanups for the ondemand governor.

[1/2] rearranges some code to avoid duplication.
[2/2] drops a governor-specific callback that's never used.

Both on top of the linux-next branch of the linux-pm.git tree from today.

Thanks,
Rafael

Drop some lines of code from od_update() by arranging the statements
in there in a more logical way.

No functional changes.

The ->freq_increase callback in struct od_ops is never invoked,
so drop it.

No functional changes.
