4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Oswald Buddenhagen <[email protected]> commit b084116f8587b222a2c5ef6dcd846f40f24b9420 upstream. Without UPF_FIXED_TYPE, the data from the PORT_AR7 uart_config entry is never copied, resulting in a dead port.
