kbuild, 0day kernel build service, outputs the warning: arch/x86/kernel/apic/io_apic.c:2211 smp_irq_move_cleanup_interrupt() warn: always true condition '(irq <= -1) => (0-u32max <= (-1))'
because irq is defined as an unsigned int instead of an int. Fix this trivial error by redefining irq as a signed int. The remaining consumers of the int are okay.
