After commit 540b8bb9c33935183ceb5bed466a42ad72b2af56:
sony-laptop: fingers off backlight if video.ko is serving this functionality
I can't set brightness on my sony laptop (nothing in /sys/class/backlight).
dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI
video driver".
The function acpi_video_backlight_support returns 0 if we should use the
vendor-specific backlight support, while non-0 if the ACPI generic should
be used. Because of this, the check introduced by the said commit appears
reversed.

C2port implements a two wire serial communication protocol (bit

boundary-scan testing on low pin-count Silicon Labs devices.
Currently this code supports only flash programming through sysfs
interface but extensions shoud be easy to add.

The Lifebook S6420 is the ICH9M-based follow-up to the S6410. The application panel
contains the following keys: lock, mobility center, eco, info.
Whilst key 4 might be more appropriate for help then key 2, I've done things the
S6410 way. I can confirm that backlight control is functional, and that the lock key
activates the Gnome screensaver as expected.

The function acpi_fujitsu_add() references

This is often because acpi_fujitsu_add lacks a __initdata

Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".
Per section 6.5.4 of the ACPI 3.0b specification,
OSPM must make Embedded Controller operation regions, accessed
via the Embedded Controllers described in ECDT, available before
executing any control method.
The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is
specified.
This eliminates a dependency of the XP/XPC drivers on having the GRU
driver insmod'd in order to insmod them, when running on an ia64-sn2
system.
On such a system the GRU driver serves no useful purpose.

Attempt to preserve fan state across sleep and hibernation if the fan
control mode is enabled.
For safety reasons, only the PWM OFF (fan at 100%) or maximum
closed-loop level (level 7) are preserved. If the fan state was set
to anything else, it will not be restored.
Also, should the fan be at PWM OFF mode at resume, it will be left at
that state (but this is extremely unlikely, no ThinkPad firmware was
ever reported to do this).
For reference, the known states used for fan control upon resume by
the firmware are either "auto" or "level 7" depending on whether the
laptop wakes due to normal conditions or a thermal emergency.

The AE_BAD_ADDRESS exception code is now unused in ACPICA.
For linux, it's only used at wmi.c and acer-wmi.c.
I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
has no special meaning. The parent functions just call AE_SUCCESS() or
AE_FAILURE() to check the return status.
So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.
