Subject: [PATCH 17/62] driver core: Convert some drivers to CLASS_ATTR_STRING
Date: Tue,  2 Mar 2010 15:28:16 -0800	[thread overview]
Message-ID: <1267572541-410-17-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <20100302230933.GA32287@kroah.com>

From: Andi Kleen <andi@firstfloor.org>

Convert some drivers who export a single string as class attribute
to the new class_attr_string functions. This removes redundant
code all over.
