What was the report?

We don't pass a 'dev' here, so the pdata.index isn't looked at. I suppose we can assign .index to -1 to be more explicit, but because there isn't a device used for registering, we won't try to use the .index. Instead we'll try to use .fw_name for clkdev, of which there won't be a clkdev lookup either. Eventually we'll fallback to the .name lookup, and it will be fine.
We need tests that exercises the 'dev' path and also the DT path and the clkdev path. I was thinking about working on that outside of the gate test though, and just having a generic clk test for that with simple clk_ops that do basically nothing.
