Linus Torvalds f69a1accfe 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.
