From 24cb233520f01971d6d873cb52c64bbbb0665ac0 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 30 Apr 2008 00:54:19 -0700 Subject: char serial: switch drivers to ioremap_nocache Simple search/replace except for synclink.c where I noticed a real bug and fixed it too. It was doing NULL + offset, then checking for NULL if the remap failed.
