From e12e6d94db24e9050821965aa75c95e8d2c65f10 Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Sat, 26 Feb 2011 10:20:31 +0100 Subject: eeepc-wmi: asus generic asus-wmi.ko module New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.
