It looks like that on Dell Latitude E6440 is WMI event 0x0012 0x0003 sent
when display changes brightness. When it happens kernel prints
"dell_wmi: Unknown WMI event type 0x12" message into dmesg.
So ignore it for now to not spam dmesg.

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
