[PATCH] via82xx: fix some coding style issues
From: Marcin Ålusarz
Date: Thu Dec 06 2007 - 16:16:21 EST
fix trivial coding style issues found by checkpatch.pl:
- assignments in if conditions
- trailing whitespaces
- lines longer then 80 characters (only a couple of them)
- spaces instead of tabs
- spaces after !
- C99 comments
- other tiny changes
Signed-off-by: Marcin Ålusarz <marcin.slusarz@xxxxxxxxx>
(patch against current mainline git, errors count fallen from
76 to 2 - these are checkpatch bugs I think)
