Merge tag 'perf-tools-fixes-for-v6.1-2-2022-11-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix 'perf stat' crash with --per-node --metric-only in CSV mode, due
   to the AGGR_NODE slot in the 'aggr_header_csv' array not being set.

 - Fix printing prefix in CSV output of 'perf stat' metrics in interval
   mode (-I), where an extra separator was being added to the start of
   some lines.

 - Fix skipping branch stack sampling 'perf test' entry, that was using
   both --branch-any and --branch-filter, which can't be used together.
