Subject: [PATCH 06/10] sysfs: prevent warning when only using binary attributes
Date: Sun, 14 Jul 2013 16:05:56 -0700	[thread overview]
Message-ID: <1373843160-3990-7-git-send-email-gregkh@linuxfoundation.org> (raw)
In-Reply-To: <1373843160-3990-1-git-send-email-gregkh@linuxfoundation.org>

From: Oliver Schinagl <oliver@schinagl.nl>

When only using bin_attrs instead of attrs the kernel prints a warning
and refuses to create the sysfs entry. This fixes that.
