Subject: perf tools: Fix pipe check regression in attr event callback
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a261e4a09a073451057e9dbe17783255ea94598d;p=openwrt%2Fstaging%2Fblogic.git

perf tools: Fix pipe check regression in attr event callback

The file factoring in builtin-inject.c object introduced regression
in attr event callback. The commit is:
  3406912 perf inject: Handle output file via perf_data_file object

Following hunk reversed the logic:
  -       if (!inject->pipe_output)
  +       if (&inject->output.is_pipe)

putting it back, following example now works:
  $ perf record -o - kill | perf inject -b | perf report -i -

Plus removing extra '&' (kudos to Arnaldo)
