From 1fc7c1ef37f86f207b4db40aba57084bb2f6a69a Mon Sep 17 00:00:00 2001 From: Kent Gibson Date: Thu, 7 Jan 2021 12:00:20 +0800 Subject: tools: gpio: fix %llu warning in gpio-watch.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
