From 15b956a0b5651bbb1217ec374fdd67291dabb2af Mon Sep 17 00:00:00 2001 From: "Lee, Chun-Yi" Date: Sat, 30 Jul 2011 17:00:45 +0800 Subject: acer-wmi: support Lenovo ideapad S205 wifi switch The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control the wifi hardware state. We also found there have a 0x78 EC register exposes the state of wifi hardware switch on the machine. So, add this patch to support Lenovo ideapad S205 wifi hardware switch in acer-wmi driver.
