From: Adrian Hunter Date: Tue, 8 Sep 2015 07:58:49 +0000 (+0300) Subject: perf evlist: Simplify propagate_maps() logic X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a69b09e2342a9c144b0291b9aeb849ab7d5843bf;p=openwrt%2Fstaging%2Fblogic.git perf evlist: Simplify propagate_maps() logic If evsel->cpus is to be reassigned then the current value must be "put", which works even if it is NULL. Simplify the current logic by moving the "put" next to the assignment.
