Merge tag 'probes-fixes-v6.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-traceHEADtorvalds/mastertorvalds/HEADmaster

Pull probe fixes from Masami Hiramatsu:

 - tprobe-events: Fix to register tracepoint correctly

   tprobe-events missed to set tracepoint data structure before
   registering callback when enabling it. This sets it correctly.

 - tprobe-events: Fix to put tracepoint_user when disable the event

   tprobe-events missed to unregister tracepoint callback when the event
   is disabled. This ensures to unregister it.
