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" * tag 'trace-fixes-v4.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Make ftrace_print_array_seq compute buf_len
