> The clk registration code here currently does:
> 
>     if (IS_ERR_OR_NULL(clk_data->clks[mux->id])) {
>             ... do clk registration ...
>     }
> 
> This extra level of nesting wastes screen real estate.
> 
> Reduce the nesting level by reversing the conditional shown above.
> Other than that, functionality is not changed.
