+Subject: [PATCH 5/6] Bluetooth: btintel: Fix bdaddress comparison with garbage
+ value
+
+Intel Read Verision(TLV) data is parsed into a local structure variable
+and it contains a field for bd address. Bd address is returned only in
+bootloader mode and hence bd address in TLV structure needs to be validated
+only if controller is present in boot loader mode.
