Subject: [PATCH 02/14] 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.
