Some platforms, such as mips64, don't map __u64 to long long unsigned
int so using %llu produces a warning:
gpio-watch.c: In function ‘main’:
gpio-watch.c:89:30: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 4 has type ‘__u64’ {aka ‘long unsigned int’} [-Wformat=]
89 | printf("line %u: %s at %llu\n",
| ~~~^
| |
| long long unsigned int
| %lu
90 | chg.info.offset, event, chg.timestamp_ns);
| ~~~~~~~~~~~~~~~~
| |
| __u64 {aka long unsigned int}
Replace the %llu with PRIu64 and cast the argument to uint64_t.
