Kent Gibson 2fe7c2f994 tools: gpio: fix %llu warning in gpio-event-mon.c 
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.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
