> The mtk_clk_register_pll_ops() currently frees the "pll" parameter.
> The function has two callers, mtk_clk_register_pll() and
> mtk_clk_register_pllfh().  The first one, the _pll() function relies on
> the free, but for the second _pllfh() function it causes a double free
> bug.
> 
> Really the frees should be done in the caller because that's where
> the allocation is.
