After looking thru the ACPI tables of various people having issues
with the bitland-mifs-wmi driver, i came to the following conclusions:

1. There seem to be multiple flavors of the Mifs interface,
distinguishable by small changes inside their WMI MOF definitions

2. The buffer format used to communicate with the ACPI-WMI firmware
operates differently than previously thought.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

Thank you :)

FYI [if applicable to your patch], as per Linus' policy change, also
fixes are mostly routed through for-next unless the fix is for a
commit introduced in the most recent cycle or is clearly a regression
fix.
