Subject: [PATCH 2/9] drivers/video/fbdev/sm501fb.c: avoid world-writable sysfs files.
Date: Tue, 22 Apr 2014 13:03:25 +0930	[thread overview]
Message-ID: <1398137612-9714-3-git-send-email-rusty@rustcorp.com.au> (raw)
In-Reply-To: <1398137612-9714-1-git-send-email-rusty@rustcorp.com.au>

In line with practice for module parameters, we're adding a build-time
check that sysfs files aren't world-writable.
