Subject: [34-longterm 134/209] ACPI: debugfs custom_method open to non-root

From: Dave Jones <davej@...hat.com>

  =====================================================================
  | This is a commit scheduled for the next v2.6.34 longterm release. |
  | If you see a problem with using this for longterm, please comment.|
  =====================================================================

commit ed3aada1bf34c5a9e98af167f125f8a740fc726a upstream

Currently we have:

  --w--w--w-. 1 root root 0 2010-11-11 14:56 /sys/kernel/debug/acpi/custom_method

which is just crazy. Change this to --w-------.

[PG: back in 2.6.34, the file was called debug.c, not debugfs.c]
