Bluetooth: hci_ldisc: Add function to wait for characters to be sent
The hci UART line discipline sends its characters in a workqueue. Some devices like the Marvell Bluetooth chips need to make sure that all queued characters are sent before switching the baudrate. This adds a function to synchronize with the workqueue. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
