    Yes, but until we have a proper infrastructure for that, we have to
    disable the smbus unhiding as a safe fix.

    If you have the time to whip up a patch to add a sane quirks-on-resume
    infrastructure, I'd be grateful. See the thread
    "[RFC] [PATCH] Execute PCI quirks on resume from suspend-to-RAM" for
    some ugly proof-of-concept.
    My main motivation was to prevent bricking my laptop. Added functionality
    is desirable, but secondary.

    Regards,
    Carl-Daniel
