I would say this fixes the latter - bindings commit which introduced
duplicated ID. If your bindings patch is backported, then the number of
IDs do not match anymore number of clocks.

Without your bindings fix, everything matches even though it is not
technically correct.

The bindings fix also needs Cc-stable.
