From: Hidetoshi Seto Date: Fri, 16 Sep 2005 04:44:56 +0000 (+0900) Subject: [IA64] mca_drv cleanup X-Git-Tag: v2.6.14-rc2~5^2~60^2 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=20305e59724381365096b6ab0a48054723367c80;p=linux-2.6-omap-h63xx.git [IA64] mca_drv cleanup There were some trailing white spaces, long lines, brackets in weird style etc. This patch cleans them up.
