Subject: [PATCH] [137/275] platform: x86: asus_acpi: world-writable procfs files

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Vasiliy Kulikov <segoon@...nwall.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.
