4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Olsa <jolsa@kernel.org>

[ Upstream commit f7fa827f5f432a0b1f34e10fc49da93aeef9f817 ]

For events we provide specific error message we need to set error column
index, PMU parser is missing that, adding it.

Before:

  $ perf stat -e cycles,krava/cycles/ kill
  event syntax error: 'cycles,krava/cycles/'
                       \___ Cannot find PMU `krava'. Missing kernel support?

After:

  $ perf stat -e cycles,krava/cycles/ kill
  event syntax error: 'cycles,krava/cycles/'
                              \___ Cannot find PMU `krava'. Missing kernel support?
