From f98fd44bebac6aa203eaf8a433d3a3ded374bae5 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Thu, 3 Jul 2014 16:17:53 +0200 Subject: [PATCH] MIPS: RB532: Fix reregistering of serial console Runtime tested on Mikrotik RB532 board. Thanks goes to Geert Uytterhoeven for the explanation of the problem. "I'm afraid this is not gonna help. When the port is unregistered, its type will be reset to PORT_UNKNOWN. So before registering it again, its type must be set again the actual serial driver, cfr. the change to of_serial.c."
