Flood of "Unexpected continuation frame (len 0)" messages

Hiya,

My Sony MDR-ZX770BN headset connected to an USB Bluetooth adapter with 
the following characteristics:

        ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of 
BCM2046 Bluetooth)
        |__ Port 1: Dev 10, If 0, Class=Wireless, Driver=btusb, 12M
            ID 0a5c:2111 Broadcom Corp. ANYCOM Blue USB-UHE 200/250
        |__ Port 1: Dev 10, If 1, Class=Wireless, Driver=btusb, 12M
            ID 0a5c:2111 Broadcom Corp. ANYCOM Blue USB-UHE 200/250
        |__ Port 1: Dev 10, If 2, Class=Vendor Specific Class, Driver=, 12M
            ID 0a5c:2111 Broadcom Corp. ANYCOM Blue USB-UHE 200/250
        |__ Port 1: Dev 10, If 3, Class=Application Specific Interface, 
Driver=, 12M
            ID 0a5c:2111 Broadcom Corp. ANYCOM Blue USB-UHE 200/250

keeps flooding my kernel log with:

[2413092.567730] Bluetooth: Unexpected continuation frame (len 0)

Is there a quirk that should be set for this adapter? Audio playback 
over Bluetooth A2DP works just fine.

Thanks!
