Subject: char serial: switch drivers to ioremap_nocache
X-Git-Tag: v2.6.26-rc1~174
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=24cb233520f01971d6d873cb52c64bbbb0665ac0;p=pandora-kernel.git

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.
