On some systems the Bluetooth Device Address (BD_ADDR) isn't stored on the Bluetooth chip itself. One way to configure the BD address is through the device tree. The btqcomsmd driver is an example, it can read the BD address from the DT property 'local-bd-address'. It is also planned to extend the hci_qca driver to support setting the BD address through the DT. To avoid redundant open-coded reading of 'local-bd-address' and error handling this series adds an API to retrieve the BD address of a device and adapts the btqcomsmd driver to use this API.
