From 71e06af26cb6ed93a58a8a835d0d70191d779343 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 14 May 2014 10:33:49 +0930 Subject: [PATCH] drivers/regulator/virtual: 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.
