The current device detection error messages are all copy & pasted - make
them more descriptive so it's easier to see where in the code a problem
occurs.

This warning confuses users, who think it is an error. Not detecting the
mail LED simply means it isn't there, so let's not unduly panic users.

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.

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.

The TM4200 series use the same method as the TM2490 series to control the
mail LED, so add a DMI based quirk for these laptops.

There is some leftover cruft from the old quirk infrastructure that causes
us to be unable to set the backlight on older laptops.

This is a driver for newer Acer (and Wistron) laptops. It adds wireless
radio and bluetooth control, and on some laptops, exposes the mail LED and
LCD backlight.
v1:
* Initial release
v2:
* Replace left over ACPI references with WMI
* Add GUID based autoloading (depends on future work to WMI)
* Add DMI based autoloading (backup solution until WMI sysfs/ class
work is available)
* Checkpatch fixes
v3:
* Add new EC quirks for Aspire 3100 & 5100, and Extensa 5220
v4:
* Simplified internal handling of WMID and AMW0 devices
* Add autodetection for bluetooth and maximum brightness on AMW0 V2 and
WMID laptops.
v5:
* Add EC quirk for Medion MD 98000
* Add autodetection for AMW0, and mail LED on AMW0 and AMW0 V2.
* Improve error handling
* Fix AMW0 V2 bluetooth and wireless, by using both WMID and AMW0 methods
to ensure that the correct value is always set.
v6:
* Fix 'use before initialisation' bug with quirks.
v7
* Fix bug on AMW0 where acer-wmi would exit if a mail LED was not
detected.
* Add Acer Aspire 9110 mail LED support
* Fix section mismatch warnings
