From 4a3ad20ccd8f4d2a0535cf98fa83f7b561ba59a9 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 24 Jan 2008 22:50:12 -0800 Subject: Driver core: coding style fixes Fix up a number of coding style issues in the drivers/base/ directory that have annoyed me over the years. checkpatch.pl is now very happy.
