[ Upstream commit c861c1be3897845313a0df47804b1db37c7052e1 ]
bm1880_clk_unregister_pll & bm1880_clk_unregister_div both try to free statically allocated variables, so remove those kfrees.
For example, if we take L703 kfree(div_hw): - div_hw is a bm1880_div_hw_clock pointer - in bm1880_clk_register_plls this is pointed to an element of arg1: struct bm1880_div_hw_clock *clks - in the probe, where bm1880_clk_register_plls is called arg1 is bm1880_div_clks, defined on L371: static struct bm1880_div_hw_clock bm1880_div_clks[]
