Merge tag 'trace-printf-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull bprintf() removal from Steven Rostedt:

 - Remove unused bprintf() function, that was added with the rest of the
   "bin-printf" functions.

   These are functions that are used by trace_printk() that allows to
   quickly save the format and arguments into the ring buffer without
   the expensive processing of converting numbers to ASCII. Then on
   output, at a much later time, the ring buffer is read and the string
   processing occurs then. The bprintf() was added for consistency but
   was never used. It can be safely removed.
