Now that you mention it, if the clocks are sorted by rating (something
your removing) then the sysfs override available listing isn't in rated
order .. So if you do have zero rated clocks you wouldn't have any idea
from looking at the available list.. It could be solved just by printing
them in rated order in the sysfs code tho.
