That's rather silly.  It isn't a build breakage, and it's not a
functional breakage.  In fact, this driver gets build and boot tested
every evening on hardware I have here in my autobuild system.

The regression is only visible if it is used on a platform with power
management support, and that's probably close to none - unless hibernate
support is enabled.  I'm just pushing up some patches which fix long
term hibernation issues on ARM.

If we apply your "lets drop stuff" argument, maybe we should drop ARM
hibernation support because its been broken for many years... obviously
that's also a rediculous suggestion.
