Should be #clock-cells instead.

This can just go onto the stack? We don't need it around after
probe.

Missed this last time. Do you use this clkdev lookup? The name is
usually supposed to be based on what the device is expecting,
instead of clk_name, and we would want some device name for the
third argument here.
