WARNING: net/rfkill/rfkill.o(.init.text+0xa2): Section mismatch in reference from the function _init_module() to the function .exit.text:_rfkill_handler_exit()

   The function __init _init_module() references
   a function __exit _rfkill_handler_exit().
   This is often seen when error handling in the init function
   uses functionality in the exit path.
   The fix is often to remove the __exit annotation of
   _rfkill_handler_exit() so it may be used outside an exit section.
