Subject: [for-linus][PATCH 0/2] fgraph: Fixes for 6.12

Fixes for function graph:

- Fix missing mutex unlock in error path of register_ftrace_graph()

  A previous fix added a return on an error path and forgot to unlock the
  mutex. Instead of dealing with error paths, use guard(mutex) as the mutex
  is just released at the exit of the function anyway. Other functions
  in this file should be updated with this, but that's a cleanup and not
  a fix.

- Change cpuhp setup name to be consistent with other cpuhp states

  The same fix that the above patch fixes added a cpuhp_setup_state() call
  with the name of "fgraph_idle_init". I was informed that it should instead
  be something like: "fgraph:online". Update that too.
