From 993bcc62ce4437c5b46f503981cd5057ae90c008 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 14 May 2014 10:33:47 +0930 Subject: [PATCH] drivers/mtd/devices/docg3.c: avoid world-writable sysfs files. In line with practice for module parameters, we're adding a build-time check that sysfs files aren't world-writable.
