[PATCH 0/5] Thunderbolt GPU fixes
Fix Thunderbolt-related issues in apple-gmux and vga_switcheroo:
Patch [1/5] ("Recognize Thunderbolt devices") has already been subjected
to a fair amount of scrutiny over at linux-pci@, I've submitted it 5 times
total since May 2016. With luck it may be in ack-able shape now.
Patch [2/5] amends apple-gmux to handle combined DP/Thunderbolt ports
properly on newer MacBook Pros.
