Subject: [PATCH 5/6] function_graph: Make fgraph_do_direct static key static

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

The static branch key "fgraph_do_direct" was not declared static but is
only used in one file. Change it to a static variable.

Fixes: cc60ee813b503 ("function_graph: Use static_call and branch to optimize entry function")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202406051711.dS1sQZ9n-lkp@intel.com/
