Subject: [PATCH 02/10] sysfs.h: add ATTRIBUTE_GROUPS() macro
Date: Sun, 14 Jul 2013 16:05:52 -0700 [thread overview]
Message-ID: <1373843160-3990-3-git-send-email-gregkh@linuxfoundation.org> (raw)
In-Reply-To: <1373843160-3990-1-git-send-email-gregkh@linuxfoundation.org>
To make it easier for driver subsystems to work with attribute groups,
create the ATTRIBUTE_GROUPS macro to remove some of the repetitive
typing for the most common use for attribute groups.
