    Subject[PATCH 5.10 151/199] tools: gpio: fix %llu warning in gpio-event-mon.c
    Date
    From: Kent Gibson <warthog618@gmail.com>

    commit 2fe7c2f99440d52613e1cf845c96e8e463c28111 upstream.

    Some platforms, such as mips64, don't map __u64 to long long unsigned
    int so using %llu produces a warning:

    gpio-event-mon.c:110:37: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘__u64’ {aka ‘long unsigned int’} [-Wformat=]
    110 | fprintf(stdout, "GPIO EVENT at %llu on line %d (%d|%d) ",
    | ~~~^
    | |
    | long long unsigned int
    | %lu
    111 | event.timestamp_ns, event.offset, event.line_seqno,
    | ~~~~~~~~~~~~~~~~~~
    | |
    | __u64 {aka long unsigned int}

    Replace the %llu with PRIu64 and cast the argument to uint64_t.
