On a related note: Using an 'enum' in an ABI structure is not portable
across architectures. This is probably fine in a UAPI as long as user
and kernel space agree on the size of an enum, but if the same
structure is used to talk to the firmware, it won't work on architectures
that have a different size for the first field.
