3.16.52-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Oswald Buddenhagen <oswald.buddenhagen@xxxxxx>
commit b084116f8587b222a2c5ef6dcd846f40f24b9420 upstream.
Without UPF_FIXED_TYPE, the data from the PORT_AR7 uart_config entry is
never copied, resulting in a dead port.
Fixes: 154615d55459 ("MIPS: AR7: Use correct UART port type")
