Subject: [PATCH net-next 06/16] net: farsync: fix the comments style issue
From: Peng Li <lipeng321@...wei.com>
Networking block comments don't use an empty /* line,
use /* Comment...
Block comments use * on subsequent lines.
Block comments use a trailing */ on a separate line.
This patch fixes the comments style issues.
