[PATCH 2/3] Bluetooth: Fix read_name updating when HCI_SETUP is not set

[johan.hedberg@gmail.com]

From: Johan Hedberg <johan.hedberg@intel.com>

The local name should only be updated as a consequence of a
hci_read_local_name if we are in the HCI_SETUP state. In all other
scenarios it should only be updated through hci_write_local_name.
