4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Guenter Roeck <[email protected]> commit fc2ca674470bbfe11d72a20a3f19fd3dc43bfca0 upstream. Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface") made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured. Unfortunately, it did not initialize the number of UARTs if LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e system has no console.
