Subject: [PATCH 3.19.y-ckt 160/170] perf pmu: Fix misleadingly indented assignment (whitespace)

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Markus Trippelsdorf <markus@...ppelsdorf.de>

commit d85ce830eef6c10d1e9617172dea4681f02b8424 upstream.

One line in perf_pmu__parse_unit() is indented wrongly, leading to a
warning (=> error) from gcc 6:

  util/pmu.c:156:3: error: statement is indented as if it were guarded by... [-Werror=misleading-indentation]

    sret = read(fd, alias->unit, UNIT_MAX_LEN);
    ^~~~

  util/pmu.c:153:2: note: ...this 'if' clause, but it is not
    if (fd == -1)
    ^~
