[PATCH v2 1/2] dell-smbios-base: Extends support to Alienware products

[PATCH v2 1/2] dell-smbios-base: Extends support to Alienware products

[Kurt Borja]

Fixes the following error:

dell_smbios: Unable to run on non-Dell system

Which is triggered after dell-wmi driver fails to initialize on
Alienware systems, as it depends on dell-smbios.

This effectively extends dell-wmi, dell-smbios and dcdbas support to
Alienware devices, that might share some features of the SMBIOS intereface
calling interface with other Dell products.

Tested on an Alienware X15 R1.

[PATCH v2 2/2] dell-wmi-base: Handle META key Lock/Unlock events

[Kurt Borja]

Some Alienware devices have a key that locks/unlocks the Meta key. This
key triggers a WMI event that should be ignored by the kernel, as it's
handled by internally the firmware.

There is no known way of changing this default behavior. The firmware
would lock/unlock the Meta key, regardless of how the event is handled.

Tested on an Alienware x15 R1.

Thinking through why this event exists, it's probably so that there can 
be a toast message or popup or something similar in Windows to show an 
icon that it was changed, which doesn't currently exist in Linux.

There was a really similar change that got committed recently to 
dell-wmi-sysman:

https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/commit/?h=fixes&id=a561509b4187a8908eb7fbb2d1bf35bbc20ec74b

The lines are identical now.  Is it also worth splitting out to a 
helper?  Not sure.

Thank you for your patches, I've applied both patches to
my review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note they will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

I will include these patches in my next fixes pull-req to Linus
for the current kernel development cycle.

Regards,

Hans
