From 12aa4c64174cb0d915cd1c7b763847c0ffa8e92c Mon Sep 17 00:00:00 2001 From: Brian Swetland Date: Wed, 27 Oct 2010 15:34:49 -0700 Subject: [PATCH] w1: don't allow arbitrary users to remove w1 devices The search/pullup/add/remove device attributes were 0666 which would allow arbitrary users to affect the 1 wire bus. Change to 0664 to prevent that. I found this patch in the Android tree, apparently this has never been sent upstream so doing it now.
