From 1696d9dc57e062ce5200f6a42a6aaada15b434bb Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Mon, 15 Jul 2013 10:15:09 +0200 Subject: ACPI: Remove the old /proc/acpi/event interface It is quite some time that this one has been deprecated. Get rid of it. Should some really important user be overseen, it may be reverted and the userspace program worked on first, but it is time to do something to get rid of this old stuff...
