Subject: [RFC PATCH 20/21] platform-x86: Split the alienware-wmi module
Split the alienware-wmi module into three files, which correspond to the
different interfaces this module exposed. The new structure roughly
works like this:
- alienware-wmi-base.c: Manages DMI quirks and will initialize the
preferred WMI driver
- alienware-wmi-alienfx.c: Manages the sysfs interface exposed by the
"alienware-wmi" platform device
- alienware-wmi-awcc.c: Manages thermal control methods present on new
Alienware and Dell devices
These three parts already worked completely independently, so the split
is done seamlessly by copying and pasting.
