Merge tag 'trace-v6.13-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:
"Two minor tracing fixes:

- Add "const" to "char *" in event structure field that gets assigned
literals.

- Check size of input passed into the tracing cpumask file.

If a too large of an input gets passed into the cpumask file, it
could trigger a warning in the bitmask parsing code"

* tag 'trace-v6.13-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing: Prevent bad count for tracing_cpumask_write
tracing: Constify string literal data member in struct trace_event_call
