The following drivers: 8250_core, atmel_serial, max310x, mcf, omap-serial and sci16is7xx implement code to handle RS485 ioctls. In order to avoid code duplication, we implement a simple ioctl handler on the serial_core layer. This handler can be used by all the other drivers instead of duplicating code. Until this is the only RS485 ioctl handler, it will try first the rs485_config callback and if it is not present it will call the driver specific ioctl.
