Subject: [PATCH 2/2] perf stat: Fix invalid output handle
Date: Wed, 30 Nov 2022 11:15:21 +0000	[thread overview]
Message-ID: <20221130111521.334152-2-james.clark@arm.com> (raw)
In-Reply-To: <20221130111521.334152-1-james.clark@arm.com>

In this context, 'os' is already a pointer so the extra dereference
isn't required. This fixes the following test failure on aarch64:

  $ ./perf test "json output" -vvv
  92: perf stat JSON output linter                                    :
  --- start ---
  Checking json output: no args Test failed for input:
  ...
  Fatal error: glibc detected an invalid stdio handle
  ---- end ----
  perf stat JSON output linter: FAILED!

Fixes: e7f4da312259 ("perf stat: Pass struct outstate to printout()")
