As noted in that change, the __counted_by\nmember must be initialized with the number of elements before the first\narray access happens, otherwise there will be a warning from each access\nprior to the initialization because the number of elements is zero. This\noccurs in exynos_clkout_probe() due to .num being assigned after .hws[]\nhas been accessed:\n\n  UBSAN: array-index-out-of-bounds in drivers/clk/samsung/clk-exynos-clkout.c:178:18\n  index 0 is out of range for type 'clk_hw *[*]'\n\nMove the .num initialization to before the first access of .hws[],\nclearing up the warning.",
