Merge tag 'probes-fixes-v6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes fixes from Masami Hiramatsu:

 - tracing/kprobes: Fix kernel-doc warnings for the variable length
   arguments

 - tracing/kprobes: Fix to count the symbols in modules even if the
   module name is not specified so that user can probe the symbols in
   the modules without module name

* tag 'probes-fixes-v6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
  tracing/kprobes: Fix symbol counting logic by looking at modules as well
  tracing/kprobes: Fix the description of variable length arguments
