Subject: [GIT PULL] probes: Fixes for v6.14-rc6

Hi Linus,

Probes fixes for v6.14-rc6:

- tprobe-events: Fix to clean up tprobe correctly when module unload
  tprobe (Tracepoint probe) event does not set TRACEPOINT_STUB to its
  'tpoint' pointer when unloading module, thus it is shown as a normal
  'fprobe' instead of 'tprobe' and never comes back.
- tprobe-events: Fix leakage of module refcount
  When a tprobe's target module is loaded, it gets the module's refcount
  in the module notifier but forgot to put it after registering the probe
  on it. Fix to get the refcount only when registering tprobe.
