3.18-stable 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.
