From 5e460c259d34af10ba0bda586afdb29f819d561f Mon Sep 17 00:00:00 2001 From: Keng-Yu Lin Date: Mon, 27 Jun 2011 18:01:11 +0100 Subject: [PATCH] UBUNTU: SAUCE: Revert: "dell-laptop: Toggle the unsupported hardware killswitch" This reverts commit a3d77411e8b2ad661958c1fbee65beb476ec6d70, as it causes a mess in the wireless rfkill status on some models. It is probably a bad idea to toggle the rfkill for all dell models without the respect to the claim that it is hardware-controlled.
