This patch is to return error code of perf_new_session function on failure instead of NULL. Test Results: Before Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 0 $ After Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 254 $ Committer notes: Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(..., session), i.e. we need to pass zero in case of failure, which was the case before when NULL was returned by perf_session__new() for failure, but now we need to negate the result of IS_ERR(session) to respect that TEST_ASSERT_VAL) expectation of zero meaning failure.
