Summary
Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hcisync: Fix queuing commands when HCIUNREGISTER is set

hcicmdsyncqueue shall return an error if HCIUNREGISTER flag has been set as that means hciunregisterdev has been called so it will likely cause a uaf after the timeout as the hdev will be freed.
