    thunderbolt: Allow loading of module on recent Apple MacBooks with thunderbolt 2 controller · a42fb351
    Knuth Posern authored
    The pci device ids listed in the thunderbolt driver are to restrictive,
    which prevents the driver from being loaded on recent Apple MacBooks
    using a thunderbolt 2 controller. In particular this prevented any
    hot-plugging functionality for thunderbolt based ethernet dongles
    (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle
    Model A1433 EMC 2590).
    
    Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver
    loads and binds to the pci device 07:00.0 System peripheral:
    Intel Corporation Device 156c which is the thunderbolt 2 controller on
    the MacBookPro12,1.
    
    Successfully tested on MacBookPro12,1. With the patch the thunderbolt
    module gets now loaded on boot. And it provides hot-plugging support both
    for a cold-plugged and a warm-plugged ethernet dongle.
