From foo@baz Tue Jul 2 12:17:06 PDT 2013
Date: Tue, 02 Jul 2013 12:17:06 -0700
To: Greg KH <gregkh@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: USB: isp1362: move debug files from proc to debugfs
Drivers should not be putting debug files in /proc/ that is what debugfs
is for, so move the isp1362 driver's debug file to debugfs.
