Merge tag 'trace-v4.4-rc4-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt: "Two more fixes: 1. The recordmcount change had an output that used sprintf() (incorrectly) when it should have been a fprintf() to stderr. 2. The printk_formats file could crash if someone added a trace_printk() in the core kernel, and also added one in a module. This does not affect production kernels. Only kernels where developers add trace_printk() for debugging can crash" * tag 'trace-v4.4-rc4-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix setting of start_index in find_next() ftrace/scripts: Fix incorrect use of sprintf in recordmcount
