perf intel-pt: Fix syntax in documentation of config option
As specified in tools/perf/Documentation/perf-config.txt, perf configuration items must be in 'key = value' format, otherwise the following error message occurs:
$ perf record -e intel_pt//u -- ls bad config file line 2 in ~/.perfconfig $ cat .perfconfig [intel-pt] mispred-all
Changing to assigning a value to the key 'mispred-all' fixes the issue:
$ perf record -e intel_pt//u -- ls [ perf record: Woken up 1 times to write data ] [ perf record: Capured and wrote 0.031 MB perf.data] $ cat .perfconfig [intel-pt] mispred-all = true
