Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core fixes from Arnaldo Carvalho de Melo:

 * The new perf_evsel__tp_sched_test 'perf test' broke the build by setting the
   'ret' variable but not using it, caught by newer gcc
   -Werror=unused-but-set-variable, fix from Namhyung Kim.

 * pevent_parse_event should return a proper PEVENT_ERRNO__ and call
   pevent_free_format on its failure path, fixes from Namhyung Kim.
