| |
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.
