There may be multiple ways of controlling the backlight on a given
machine. Allow drivers to expose the type of interface they are
providing, making it possible for userspace to make appropriate policy
decisions.

dmi_check_system() walks the table running matching functions until
someone returns non zero or we hit the end.
This patch makes dmi_check_cb to return 1 so dmi_check_system() return
immediately when a match is found.

Found the N014, N051 and CR620 are must the same with N034 there are

There have some MSI netbook change devices state by EC when user press
wlan/bluetooth/wwan function keys. So, add a i8042 filter to sync sw
state with BIOS when function keys pressed.

Values such as max_brightness should be set before backlights are
registered, but the current API doesn't allow that. Add a parameter to
backlight_device_register and update drivers to ensure that they
set this correctly.

Implement the resume method for set the load SCM flag after system reusme.
Without this patch, the wifi function key on SCM model will back to BIOS
control mode then confuse with the userland software control.

Some MSI 3G netbook only have one fn key to control Wlan/Bluetooth/3G,
those netbook will load the SCM (windows app) to disable the original
Wlan/Bluetooth control by BIOS when user press fn key, then control
Wlan/Bluetooth/3G by SCM (software control by OS). Without SCM, user
cann't on/off 3G module on those 3G netbook.
On Linux, msi-laptop driver will do the same thing to disable the
original BIOS control, then might need use HAL or other userland
application to do the software control that simulate with SCM.
e.g. MSI N034 netbook

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.
The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.
In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
