Subject[PATCH 053/173] platform: x86: asus_acpi: world-writable procfs files
2.6.27.59-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Vasiliy Kulikov <segoon@openwall.com>

commit 8040835760adf0ef66876c063d47f79f015fb55d upstream.

Don't allow everybody to change ACPI settings. The comment says that it
is done deliberatelly, however, the comment before disp_proc_write()
says that at least one of these setting is experimental.
