Bluetooth: btqcomsmd: use HCI_QUIRK_USE_BDADDR_PROPERTY
Browse files Browse the repository at this point in the history
Use the HCI_QUIRK_USE_BDADDR_PROPERTY quirk to let the HCI
core handle the reading of 'local-bd-address'. With this there
is no need to set HCI_QUIRK_INVALID_BDADDR, the case of a
non-existing or invalid fwnode property is handled by the core
code.
