Merge tag 'trace-fixes-v4.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing fix from Steven Rostedt:
 "The newly added ftrace_print_array_seq() function had a bug in it.
  Luckily, the only user of it didn't make the 4.1 merge window.

  But the helper function should be fixed before 4.2 when the users
  start coming in"
