Subject: acer-wmi: support Lenovo ideapad S205 wifi switch
From: "Lee, Chun-Yi" <[email protected]>
commit 15b956a0b5651bbb1217ec374fdd67291dabb2af upstream.
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.
