The exit function neglects to remove debugfs entries, leading to a BUG
on reload.

Arjan van de Ven 83097aca85 Fix oops in acer_wmi driver (acer_wmi_init)
The acer_wmi driver does a DMI scan for quirks, and then sets flags into the
"interface" datastructure for some cases. However, the quirks happen real early
before "interface" is per se initialized from NULL.

The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the
end, when "interface" has it's final value.

Carlos Corbacho 5c742b45dd acer-wmi: Fix wireless and bluetooth on early AMW0 v2 laptops
In the old acer_acpi, I discovered that on some of the newer AMW0 laptops
that supported the WMID methods, they don't work properly for setting the
wireless and bluetooth values.

So for the AMW0 V2 laptops, we want to use both the 'old' AMW0 and the
'new' WMID methods for setting wireless & bluetooth to guarantee we always
enable it.

This was fixed in acer_acpi some time ago, but I forgot to port the patch
over to acer-wmi when it was merged.

(Without this patch, early AMW0 V2 laptops such as the Aspire 5040 won't
work with acer-wmi, where-as they did with the old acer_acpi).

AK: fix compilation

Carlos Corbacho 81143522aa acer-wmi: Add debugfs file for device detection
Add a debugfs file for showing the full results of the method we use to
detect devices on WMID laptops.

This should be useful in the case that a Linux user gets an Acer laptop
with 3G support (and/ or people who enjoy ripping their wireless cards out)
so we can get some feedback on how this value changes in these cases.

(At the moment, we always enable the wireless and 3G control. In the case
of the former, this is fairly safe. In the case of the latter though,
trying to toggle this device if it doesn't exist on a laptop causes ACPI
warnings/ errors).

To summarise: If you have an Acer laptop with a built in 3G card, please
report back the value from this file.

Carlos Corbacho 9991d9f2bc acer-wmi: Blacklist backlight on Acer Aspire 1520 & 1360 series
A newer BIOS for these laptops adds ACPI-WMI support to them. However, it does
not add support for the backlight via the EC, and we have no way to detect
this on older machines, so blacklist it from them.

Carlos Corbacho 343c00422d acer-wmi: Rename mail LED correctly & remove hardcoded colour
The mail LED name for acer-wmi currently hardcodes in the colour as green.
This is wrong, since many of the newer laptops now come with an orange
LED, and we have no way of telling what colour is used on a given system.

Also, rename the mail LED to be inline with the current recommendations of
the LED class documentation.

Sam Ravnborg 7560e38565 acer-wmi: fix section mismatch warnings
Fix following warnings:
WARNING: vmlinux.o(.text+0x672615): Section mismatch in reference from the function acer_platform_remove() to the function .exit.text:acer_backlight_exit()
WARNING: vmlinux.o(.devinit.text+0x1e859): Section mismatch in reference from the function acer_platform_probe() to the function .init.text:acer_led_init()
WARNING: vmlinux.o(.devinit.text+0x1e878): Section mismatch in reference from the function acer_platform_probe() to the function .init.text:acer_backlight_init()

Remove __exit annotation from acer_backlight_exit(). We cannot reference
a __exit annotated function from non __exit functions.

acer_led_init() and acer_backlight_init() where both annotated __init but
used from a __devinit function. This would result in an oops should
gcc drop their inlining and the module are hot plugged.

Fix by annotating acer_led_init() and acer_backlight_init() __devinit.
