pointer to the uart low level driver structure for this port
uart port structure describing the port
Register UART settings with the specified low level driver. Detect the type of the port if UPF_BOOT_AUTOCONF is set, and detect the IRQ if UPF_AUTO_IRQ is set.
We try to pick the same port for the same IO base address, so that when a modem is plugged in, unplugged and plugged back in, it gets allocated the same port.
Returns negative error, or positive line number.
