After this

It's okay to use

if (idx >= JH7100_CLK_END)
return dev_err_probe(priv->dev, -EINVAL, "invalid clock
index %u\n", idx);
Ditto for other similar cases.

I still consider that usual pattern, i.e.
while (idx--)
clk_hw_unregister(&priv->reg[idx].hw);
but since you are pushing hard for your variant I'll leave it to the
