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.
