CC kernel/irq/autoprobe.o
kernel/irq/autoprobe.c: In function ʽprobe_irq_onʼ:
kernel/irq/autoprobe.c:74:8: error: void value not ignored as it ought to be
if (irq_activate_and_startup(desc, IRQ_NORESEND))
^~~~~~~~~~~~~~~~~~~~~~~~
Just
irq_activate_and_startup(desc, IRQ_NORESEND);

cures the warning and at least the first bootup was working otherwise
too.
