[PATCH 0/5] Thunderbolt material for v4.20

[Lukas Wunner]

Thunderbolt material for v4.20, comprising:

* A fix to skip disabled ports on tunnel establishment.  I am not aware
  that this has caused breakage in the real world so far, so no need to
  apply to v4.19 or backport to stable.

* Obtain PCI slot number from DROM and use it to correlate PCI devices
  with Thunderbolt ports.

* I am nominating myself as co-maintainer, see commit message for the
  reasons.

Regarding the driver's verbosity which Stephen Hemminger and Mika
Westerberg have taken exception to:

* Patch [2/5] logs the PCI slot number as well as data whose purpose is
  unknown at KERN_INFO severity.  I am not opposed to log the former at
  KERN_DEBUG severity, but the latter must stay at KERN_INFO to allow us
  to collect the data of various Thunderbolt devices in the wild and
  reverse-engineer its meaning.  If Intel divulges the data's meaning then
  it need no longer be dumped.  This would be ideal for everyone involved.

* Patch [4/5] logs a message at KERN_INFO severity whenever a PCI device
  correlates or no longer correlates with a Thunderbolt port.  I am not
  opposed to toning this down to KERN_DEBUG, subject to the introduction
  of tb_port_dbg().

Thanks,

Lukas
