The Kconfig currently controlling compilation of this code is:
arch/x86/Kconfig:config NET5501
arch/x86/Kconfig: bool "Soekris Engineering net5501 System Support (LEDS, GPIO, etc)"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity, so that when reading
the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Since module_init translates to device_initcall in the non-modular

We replace module.h with moduleparam.h since the file does declare
some module parameters, and leaving them as such is currently the
easiest way to remain compatible with existing boot arg use cases.

It seems that there was an error with the active_low = 1 for the
LED, since it should be set to 0 (meaning that active is high,
since 0 is false, hence the confusion.
The wiki article about it confuses it, since it contradicts itself,
regarding what turns on the LED.
I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED
behave correctly, where "none" turns it off, and "default-on" turns it on,
when echoed onto the trigger "file" in /sys/class/leds.

Pull x86 platform driver updates from Matthew Garrett:
"Some significant updates to samsung-laptop, additional hardware
support for Toshibas, misc updates to various hardware and a new
backlight driver for some Apple machines."
Fix up trivial conflicts: geode Geos update happening next to net5501
support, and MSIC thermal platform support added twice.

Trivial platform driver for Traverse Technologies Geos and Geos2
single-board computers. Uses SMBIOS to identify platform.
Based on progressive revisions of the leds-net5501 driver that
was rewritten by Ed Wildgoose as a platform driver.
Supports GPIO-based LEDs (3) and 1 polled button which is
typically used for a soft reset.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs
Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also
This driver is inspired by leds-net5501.c by Alessandro Zummo.
Ideally, leds-net5501.c should also be moved to platform/geode.
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.
