Subject: [5.2.0-rcx] Bluetooth: hci0: unexpected event for opcode

In 5.2.0-rcx I see a new error message on startup probably after
loading the Bluetooth firmware:
[    1.609460] Bluetooth: hci0: unexpected event for opcode 0xfc2f

The error message goes away if I revert following patch:
f80c5dad7b64 Bluetooth: Ignore CC events not matching the last HCI command

Thanks, Jörg
