Ashok Reddy Soma 99b46477e3 clk: Dont return error when assigned-clocks is empty or missing
There is a chance that assigned-clock-rates is given and assigned-clocks
could be empty. Dont return error in that case, because the probe of the
corresponding driver will not be called at all if this fails.
Better to continue to look for it and return 0.
