Yes, on purpose. This patch is an API conversion to let the init()
callback of the clock ops return an error code or 0.

The patch is not meant to change anything in the prior behavior of the
clock drivers which is why every exit path return 0 with this change.

IOW, yes there are all returning 0 for now, but it will eventually
change.
