The patch below contains the following possible cleanups:
- make needlessly global code static
- remove the following EXPORT_SYMBOL'ed but unused functions in
hci_core.c:
- hci_suspend_dev
- hci_resume_dev
- hci_register_cb
- hci_unregister_cb
Please comment on which of these changes are correct and which conflict
with pending patches.
