Bluetooth: mgmt: Add local name information to read_info reply
This patch adds the name of the adapter to the reply of the read_info management command. The management messages reserve 249 bytes for the name instead of 248 (like in the HCI spec) so that there is always a guarantee that it is nul-terminated. That way it can safely be passed onto string manipulation functions. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
