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.

The driver now supports the Compal JHL90 (which I use) and it has some
added features. The biggest novelties are a battery interface
(power_supply) and a temperature and fan control interface (hmwon). It
also adds a power-off feature to the backlight subsystem and it exports a
few files that can enable/disable wake_on_XXX events.
Much of the original code of the old features is still there, but I've
changed some names to keep the naming more coherent with the added
functionalities. (Sorry for the huge patch)
Some technical stuff about the new driver:
First of all, I'm not sure if the extra features also work on the other
Compal boards. Currently they only get enabled if the DMI data indicates
you are on a JHL90 board.
Secondly, I've noticed a quirk in my fan controller. I have to re-send
the wanted pwm-level to the controller every so often. If I don't do
this, the fanspeed will slowly rise until after a couple of minutes it's
at full speed. (Note that every normal userland application will probably
update the pwm-level every so often anyway, based on temperature readings,
so this might not be an issue in practice) If this turns out to be a
problem with all the controllers, maybe we should implement a kernel timer
and have the driver re-send the pwm level every XX seconds to make this
transparent to userspace? (However, I couldn't immediately find a way to
do this cleanly.)
Additional information can be found in the source comments.

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.

This drops the support for manually groking the files in sysfs
to turn on and off the WLAN and BT for Compal laptops in favor
of platform rfkill support.
It has been combined into a single patch to not introduce regressions
in the process of simply adding rfkill support

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>
