Subject: [PATCH] Bluetooth: hci_qca: Set BDA quirk bit if fwnode exists in DT
Date: Tue, 23 Jan 2024 12:45:23 +0530
Message-ID: <20240123071523.23480-1-quic_janathot@quicinc.com>
Precedence: bulk

Content-Type: text/plain

This change is done to avoid BT not to go UNCONFIGURED state when BDA
fwnode is not available in DT for QTI SOCs.
