The top-level functions gb_init() and gb_exit() are tagged with __init and __exit, respectively. These functions call a few other functions that are similarly used only at initialization and termination time. So mark those functions accordingly. Note that, because gb_ap_exit() and gb_debugfs_cleanup() are called by gb_init() in error paths, these functions cannot be declared with the __exit attribute.
