Peter Wu c166b27e68 Change license to GPLv2+ 
The Linux kernel is licensed under GPLv2. As GPLv3 and GPLv2 are incompatible in
some way, just license bbswitch as GPL 2.0 or (at your choice) any latter
version. Note: I wrote all code of bbswith.c, so I am entitled to change the
license and do not need permission from other authors (as there are not any).

Request made by Ludwig Nussel.

Peter Wu 3e50c7b118 Do not check for nvidia DSM on igd handle 
Just in case the integrated video ACPI handle cannot be found. This is a safety
net for those who try bbswitch on an incompatible machine. I do not know any of
such machinees, but it looks good.

Peter Wu 5593d95193 Linux 3.8 compatibility hack 
Since the following commit, the device would not turn off because the power
state is unknown. Until a fix is released in Linux (or until I know what
better to do), I just assume the power state D0.

commit ddc150f7a33ae0c9cb16eaac3641abc00f56316f
Author: Lv Zheng <lv.zheng@intel.com>
Date:   Fri Nov 16 02:46:28 2012 +0100

    ACPI / PM: Add check preventing transitioning to non-D0 state from D3.

    No power transitioning from D3 state up to a non-D0 state is allowed
    so make acpi_device_set_power() fail and complain if such a transition
    is attempted.

Lekensteyn 0ec41fa2da Support Optimus machines through WMMX (GH-2) 
This should finally support machines like the Lenovo Y570. WMMX methods should
be more reliable than direct DSM probing so let's try that before calling DSM
directly.

Lekensteyn 11ddd3469f Add support for WMMX method 
This should support at least the Lenovo Ideapad Y470 and Y570. It probes the
WMMX method before calling the _DSM method directly since that method should
work for all machines that support the NVIDIA DSM.

Lekensteyn e16cdf561b bbswitch: Support for legacy _DSM function 
Newer Optimus laptops seems to use a _DSM method which is quite standard. This
is referred to as "Optimus DSM" in some DSDT files and must be called before the
discrete nVidia graphics card is turned off. Other (older?) laptops use a
different UUID, revision ID and arguments which actually enables or disables a
device. The right _DSM arguments is detected during the module initialization.
