  devices (Sui Jingfeng)

- Fix a vmd check for multi-function devices (Ilpo Järvinen)

- Add PCI_HEADER_TYPE_MFD and use it to replace literals (Ilpo Järvinen)

- Use acpi_evaluate_dsm_typed() instead of open-coding it (Andy Shevchenko)

- Keep .remove() and .probe() callbacks (previously marked __init) in case
  they're used via sysfs (Uwe Kleine-König)
