From ea04b240d93d2fab5b8251a218913cd0a1666a32 Mon Sep 17 00:00:00 2001 From: Philippe Coval Date: Sat, 2 May 2015 15:14:08 +0200 Subject: [PATCH] ideapad_laptop: Add Lenovo G40-30 to devices without radio switch Lenovo G40-30 does not provide any physical radio switch to user. Therefore disable the rfkill switch identically to the Yoga 2 approach. (Note for later, models ids are sorted alphabetically). Benefit is to make wireless available again without unloading module. It was tested successfully on 4.1.0-rc1 base with this model: (LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).
