Some cases the wrong type was used for errors and checks can be
done more cleanly.

orted to a sysfs attribute by
the WMI bus in "required_buffer_size".
The API for interacting with this interface is defined in documentation
as well as the WMI uapi header provides the format of the structures.

operate over WMI-ACPI will use an ACPI OperationRegion
for a buffer of data storage when SMM calls are performed.
This is a safer approach to use in kernel drivers as the SMM will
only have access to that OperationRegion.

f the data
should not be relied upon.
For the remaining data set vectors, continue to notate a warning
in undefined results, but as those are fields that the descriptor
intended to refer to other applications, don't fail if they're new
values.

Method type WMI objects need to be able to describe the size of
the interface that they will expect to use.
Export this information to sysfs and allow vendor drivers to
set it.
