From b8e7e40abeac49644fec4a4f52ffe74c7b05eca0 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 28 May 2009 14:01:35 +0100 Subject: [PATCH] 8250: Fix oops from setserial If you setserial a port which has never been initialised we change the type but don't update the I/O method pointers. The same problem is true if you change the io type of a port - but nobody ever does that so nobody noticed! Remember the old type and when attaching if the type has changed reload the port accessor pointers. We can't do it blindly as some 8250 drivers load custom accessors and we must not stomp those.
