Hi all,

This series provides cleanups and few improvements for DisplayPort
tunneling. First of all we increase the DPRX capabilites read timeout to
cope with the fact that graphics driver may be runtime suspended. Secondly
we move the DPRX negotiation to happen in a separate worker to allow
forward progress even if the graphics driver is not yet loaded (this is
kind if rare case but common in Intel Graphics CI).

Mika Westerberg (12):
  thunderbolt: Drop doubled empty line from ctl.h
  thunderbolt: Log config space when invalid config space reply is received
  thunderbolt: Debug log an invalid config space reply just once
  thunderbolt: Increase DPRX capabilities read timeout
  thunderbolt: Make tb_tunnel_one_dp() return void
  thunderbolt: Show path name in debug log when path is deactivated
  thunderbolt: Rework how tunnel->[init|deinit] hooks are called
  thunderbolt: Drop tb_tunnel_restart()
  thunderbolt: Pass reason to tb_dp_resource_unavailable()
  thunderbolt: Move forward declarations in one place
  thunderbolt: Rework tb_tunnel_consumed_bandwidth()
  thunderbolt: Handle DisplayPort tunnel activation asynchronously
