Como se señaló en ese cambio, el miembro __counted_by debe inicializarse con la cantidad de elementos antes de que ocurra el primer acceso a la matriz; de lo contrario, habrá una advertencia de cada acceso antes de la inicialización porque la cantidad de elementos es cero. Esto ocurre en clk_dvp_probe() debido a que ->num se asigna después de que se haya accedido a ->hws: UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2 El índice 0 está fuera del rango para el tipo 'struct clk_hw *[] __counted_by(num)' (también conocido como 'struct clk_hw *[]').
