Subject: [PATCH] perf check-headers.sh: Fix check-headers.sh opts assignment
Date: Wed, 21 Mar 2018 15:05:15 +0100
Message-ID: <20180321140515.2252-1-jolsa@kernel.org> (raw)

Currently opts variable is not zero-ed and we keep
on adding to it, ending up with:

  $ check-headers.sh 2>&1
  + opts=' "-B"'
  + opts=' "-B" "-B"'
  + opts=' "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B" "-B" "-B"'

Fixing this by initializing the opts variable.
