tools/gpio/gpio-event-mon: fix warning
PRIu64 is defined in user space to match libc's uint64_t definition. However, gpioevent_data structure in the kernel is defined using the kernel's own __u64 type. gpio-event-mon.c: In function ‘monitor_device’: gpio-event-mon.c:102:19: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘__u64 {aka long long unsigned int}’ [-Wformat=] fprintf(stdout, "GPIO EVENT %" PRIu64 ": ", event.timestamp); ^~~~~~~~~~~~~~ LD /tmp/kselftest/gpiogpio-event-mon-in.o LINK /tmp/kselftest/gpiogpio-event-mon Fix is to replace PRIu64 with llu, which we know is what the kernel uses for __u64.
