Subject: perf hists browser: Change print format from %lu to %PRIu64
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e641f696ebe4514efac00d1f4a485a06c8e94eea;p=openwrt%2Fstaging%2Fblogic.git

perf hists browser: Change print format from %lu to %PRIu64

The nr_events variable in tools/perf/ui/browsers/hists.c is of type u64,
so the print format (%lu) causes 'perf report' to show 0 event count
when running with 32-bit userspace without redirection.

This patch fixes that problem by printing nr_events as PRIu64.
