Subject: [PATCH] cpmac: fix all checkpatch errors and warnings

From: Florian Fainelli <[email-masked]>
Date: Sun, 8 Aug 2010 22:09:39 +0200

This patches fixes a couple of checkpatch warnings and errors:
- lines over 80 columns
- printk() instead of pr_cont()
- assignments in tests (if ((foo == bar())))
