[PATCH 02/15] perf evlist: Simplify propagate_maps() logic

From: Arnaldo Carvalho de Melo
Date: Tue Sep 15 2015 - 11:09:16 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

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.
