From 0b37004dd0113db3b23840b4fd8835dae2395acc Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 24 Aug 2011 15:24:54 -0700 Subject: [PATCH] Revert "tty: of_serial: add support for the DesignWare 8250" This reverts commit 14a8d47d4e9f51372996914c16bdbf1c34e209b5. It causes a build error that needs to be resolved differently.
