- Apply Borislav Petkov's patch (convert the fancmd[] array to a real
struct thus disambiguating command handling and making code more
readable.)
- Add BIOS product to BIOS table as AOA110 and AOA150 have different

- Add force_product parameter to allow forcing different product
- fix linker warning caused by "acerhdf_drv" not being named
"acerhdf_driver"

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices. This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket. This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.

This adds Topstar Laptop Extras ACPI driver. It enables hotkeys
functionality with Topstar N01 netbook. Besides hotkeys there are
other functions exposed by its ACPI firmware, but for now only
hotkeys reporting on Topstar N01 is supported. Topstar is a chinese
manufacturer, its website can be currently reached at

Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.
This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.
Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.
For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).
So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite. We have no use for that, and
I know of exactly ZERO users of that attribute, anyway. Start the
process of getting rid of it.

Fix some locking, avoid exiting the kthread before kthread_stop() is
called on it, and clean up the hotkey poll routines a little bit.
Also, restore bits in the firmware mask after hotkey_source_mask is
changed. Without this, we leave events disabled...

X40 (firmware 1V) and T41 (firmware 1R) have been confirmed to work
well with the new defaults, so we can stop pestering people to confirm
that fact.
For now, whitelist just these two firmware types. It is best to have
at least one more firmware type confirmed for Radeon 9xxx and Intel
GMA-2 ThinkPads before removing the confirmation requests entirely.

Due to rounding and clipping, exposure and gain settings do not map to
unique register values. Rather than read the registers and report gain
and exposure that may be different than the values that were set, just
cache the latest values that were set and report them. Reduce exposure
range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever.
Remove vestiges of driver signal processing that is now handled by
libv4l.
