On UART attached devices we do: 1. btbcm_initialize() 2. Setup UART baudrate, etc. 3. btbcm_finalize() After our previous changes we can now also use btbcm_finalize() from the btbcm_setup_patchram() function used on USB devices without any functional changes. This completes unifying the USB and UART paths as much as possible. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
