From 56b7f325db139c9255b1eb1d1e741576d5f8fa34 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 2 Jun 2023 10:19:12 +0200 Subject: Bluetooth: hci_bcm: do not mark valid bd_addr as invalid A recent commit restored the original (and still documented) semantics for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address is considered invalid unless an address is provided by firmware. This specifically means that this flag must only be set for devices with invalid addresses, but the Broadcom driver has so far been setting this flag unconditionally. Fortunately the driver already checks for invalid addresses during setup and sets the HCI_QUIRK_INVALID_BDADDR flag. Use this flag to indicate when the address can be overridden by firmware (long term, this should probably just always be allowed).
