[PATCH RESEND 0/2] Bluetooth: fix debugfs registration

Posted by Johan Hovold 2 years, 8 months ago

The HCI controller debugfs interface is created during setup or when a
controller is configured, but there is nothing preventing a controller
from being configured multiple times (e.g. by setting the device
address), which results in a host of errors in the logs:

	debugfs: File 'features' in directory 'hci0' already present!
	debugfs: File 'manufacturer' in directory 'hci0' already present!
	debugfs: File 'hci_version' in directory 'hci0' already present!
	...
	debugfs: File 'quirk_simultaneous_discovery' in directory 'hci0' already present!

The Qualcomm driver suffers from a related problem for controllers with
non-persistent setup.
