[PATCH] Thunderbolt 2 driver for recent Apple MacBooks

[Knuth Posern]

Hi,

This patch is submitted for upstream inclusion.
This is a first for me, so I hope the format of this mail is convenient.

Thanks to Greg and Andreas the attached patch (diff -up) fixes the bug:
https://bugzilla.kernel.org/show_bug.cgi?id=100191

The pci device ids listed in the tb driver are to restrictive, which
prevents the driver from being loaded. We have had a similar issue
with the new Mac mini.

Changing the subvendor and subdevice to PCI_ANY_ID in
	drivers/thunderbolt/nhi.c
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.


Cheers,

Knuth.
