This patch creates a new file named "bluetooth" under /proc/acpi/asus/.
This file controls both the internal Bluetooth adapter's presence on the
USB bus and the associated LED.
echo 1 > /proc/acpi/asus/bluetooth to enable, 0 to disable.
Additionally, the patch add support for Asus W5A, the first model that uses
this feature.

This patch updates the version string, copyright notices and does
whitespace cleanup (it looks weird, blame Lindent).

- Use it instead of acpi_bus_get_device() in acpi_video_bus_notify()
and use the one from struct acpi_video_device in
acpi_video_device_notify().

While trying to look for superfluous I/O accesses that can be optimized
away, I stumbled upon this ACPI sleep I/O access and couldn't figure out
why the hell this dummy op was necessary.
After more than one hour of internet research, I had collected a sufficient
number of documents (among those very old kernel versions) that finally
told me what this dummy read was about: STPCLK# doesn't get asserted in time
on (some) chipsets, which is why we need to have a dummy I/O read to delay
further instruction processing until the CPU is fully stopped.

Only if bus master activity is going on at the present, we should avoid
entering C3-type sleep, as it might be a faulty transition. As long as the
bm_activity bitmask was based on the number of calls to the ACPI idle
function, looking at previous moments made sense. Now, with it being based on
what happened this jiffy, looking at this jiffy should be sufficient.

Do not assume there was bus mastering activity if the idle handler didn't get
called, as there's only reason to not enter C3-type sleep if there is bus
master activity going on. Only for the "promotion" into C3-type sleep bus
mastering activity is taken into account, and there only current bus mastering
activity, and not pure guessing should lead to the decision on whether to
enter C3-type sleep or not.
Also, as bm_activity is a jiffy-based bitmask (bit 0: bus mastering activity
during this juffy, bit 31: bus mastering activity 31 jiffies ago), fix the
setting of bit 0, as it might be called multiple times within one jiffy.
