I'm sorry that I didn't notice this problem and these patches should be merged
into a series.

I have a question that what if CONFIG_PM is not defined?
Since I have met runtime PM before in the patch
a31eda65ba21 ("net: fec: fix clock count mis-match").
I learned there that in some cases CONFIG_PM is not defined so runtime PM
cannot take effect.
Therefore, undo operations should still exist in remove functions.
