arm64 defconfig spits out the following compiler warning from the ITS driver: In file included from include/linux/bitmap.h:9:0, from drivers/irqchip/irq-gic-v3-its.c:18: drivers/irqchip/irq-gic-v3-its.c: In function ‘its_create_device’: include/linux/kernel.h:716:17: warning: comparison of distinct pointer types lacks a cast (void) (&_max1 == &_max2); \ ^ drivers/irqchip/irq-gic-v3-its.c:1056:12: note: in expansion of macro ‘max’ nr_ites = max(2, roundup_pow_of_two(nvecs)); Fix the warning by specifying the decimal constant `2' explicitly as an unsigned long type.
