From: Jaeden Amero <jaeden.amero@xxxxxx> In all functions other than atmel_serial_probe_fifos, atmel_serial_probe, and atmel_console_init, the name "port" is used to refer to an instance of struct uart_port. In many of these functions, "atmel_port" is used to refer to an instance of struct atmel_uart_port. We make the use of the name "port" consistent by making atmel_serial_probe_fifos, atmel_serial_probe, and atmel_console_init use "atmel_port" to refer to an instance of struct atmel_uart_port instead of the previous name of "port".
