The tp_features.bright_acpimode will not be set correctly for brightness
control because ACPI_VIDEO_HID will not be located in ACPI. As a result,
a duplicated key event will always be sent. acpi_video_backlight_support()
is sufficient to detect standard ACPI brightness control.

The XO-1 rfkill driver should only send EC commands when changing
between blocked/unblocked state.

The rfkill switch is asked to be unblocked on every resume (even when
the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET
command here upsets the resume sequence of the libertas driver. Adding
the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume
behaviour.

The rfkill state is maintained by the hardware over suspend/resume
so no extra consideration is needed here.

compilation would fail with

because a section containing const variables is marked read only and so

Due to new supported hardware, of which the actual temperature limits of
processor, harddisk and other components are unknown, it feels safer with
lower fanon / fanoff settings.

It won't change much for most people, already using acerhdf, as they use
their own fanon/fanoff variable settings when loading the module.

Furthermore seems like kernel and userspace tools have been improved to
work more efficient and netbooks don't get so hot anymore.

In drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() the call
to dmi_first_match() may fail and return NULL. If it does return NULL,
then we'll be dereferencing a NULL pointer in the rfkill_alloc() call
where we do 'system_id->driver_data' --> KABOOM!

Avoid that problem by testing for a NULL return value from
dmi_first_match() and bailing out if it fails.

I was a bit uncertain about what to return in the failure case. In the
end I settled for -ENXIO as the most logical error to return.

Due to some implementation reasons, ASUS ET2012 All-in-One machines
can't report the correct backlight power status, it will always return
1. To track the backlight power status correctly, we have to store the
status by ourselves.

BTW, by the BIOS design, the backlight power will be turn on/off
sequently, no matter what the value of the parameter will be.
More over, the brightness adjustment command will turn on the backlight
power. Those behaviors will make us fail to track the backlight power
status.
For example, While we are trying to turn on the backlight power,
we will send out the brightness adjustment command and then trying to
figure out if we have to turn on the backlight power, then send out
the command. But, the real case is that, the backlight power turns on
while sending the brightness adjustment command, and then we send out
the command to turn on the backlight power, it actually will turn off
the backlight power and the backlight power status we recorded becomes
wrong. So, we have to seperate these two commands by a if statement.

Some ASUS ET2012E/I All-in-One machines that use a scalar board
to control the brightness, and they only accept brightness up and down
command. So, I introduced a get_scalar_command() function to pass the
command to the scalar board through WMI.

Besides, we have to store the brightness value locally, for we need the
old value to know the brightness value is increasing or decreasing.

BTW, since there is no way to retrieve the actual brightness(it would be
a fixed value), and the max brightness value would be fixed to 1, so we
have to keep passing the brightness up/down command when we reached the
max brightness value or 0.
