[PATCH v3 0/2] Bluetooth: fix race during h4 bluetooth initialization

[Jonathan Rissanen <jonathan.rissanen@axis.com>]

Hi,

This series fixes a race condition that causes hci events to sometimes
be ignored during h4 initialization.

The first patch clears the HCI_UART_PROTO_INIT bit if device
registration fails. This is needed to prevent the second patch from
introducing a possible null pointer dereference.

The second patch contains the fix for the race condition.
