As noted in that change, the __counted_by member must be\ninitialized with the number of elements before the first array access\nhappens, otherwise there will be a warning from each access prior to the\ninitialization because the number of elements is zero. This occurs in\nclk_dvp_probe() due to ->num being assigned after ->hws has been\naccessed:\n\n UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2\n index 0 is out of range for
