From 28f089c18464810ec9e91ee10a89adbb02ad7765 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Mon, 23 Jun 2008 17:22:58 -0300 Subject: [PATCH] rfkill: handle SW_RFKILL_ALL events Teach rfkill-input how to handle SW_RFKILL_ALL events (new name for the SW_RADIO event). SW_RFKILL_ALL is an absolute enable-or-disable command that is tied to all radios in a system.
