From 8440838bc5337243917f13bc14ea2445da5e0197 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 13 Oct 2008 10:45:26 +0100 Subject: serial: fix device name reporting when minor space is shared between drivers The multiple drivers share the minor space occupied by a particular major number, the actual index within the device name's space is indicated by the tty_driver->name_base + uart_port->line Another usable formula is (uart_driver->minor - MINOR_BASE) + port->line Use those to print the device names properly in such situations in serial_core.c and 8250.c Signed-off-by: David S.
