  thunderbolt: Fix old style declaration warning (2020-07-02 14:50:11 +0300)

----------------------------------------------------------------
thunderbolt: Changes for v5.9 merge window

This includes following Thunderbolt/USB4 changes for v5.9 merge window:

  * Improvements around NHI (Native Host Interface) HopID allocation

  * Improvements to tunneling and USB3 bandwidth management support

  * Add KUnit tests for path walking and tunneling

  * Initial support for USB4 retimer firmware upgrade

  * Implement Thunderbolt device firmware upgrade mechanism that runs
    the NVM image authentication when the device is disconnected.

  * A couple of small non-critical fixes

----------------------------------------------------------------

Please notice when merged with kunit-next tree there will be a build
error because the one member (allocation) of struct kunit_resource was
renamed with linux-next commit d4cdd146d0db ("kunit: generalize
kunit_resource API beyond allocated resources"). Linux-next carries a
fix that is at the end of this email to solve the issue (from Stephen
Rothwell).

Let me know if you prefer that I merge kunit-next branch to my -next
branch and resolve it there first.

Thanks!
