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.

printf: Remove unused 'bprintf'
