Subject: perf tools: Introduce hists__inc_nr_samples()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1844dbcbe78503e0f4a8996d69da725d5e7a5177;p=openwrt%2Fstaging%2Fblogic.git

perf tools: Introduce hists__inc_nr_samples()

There're some duplicate code for counting number of samples.  Add
hists__inc_nr_samples() and reuse it.
