Thanks for the explanations.
On the one hand it is a fine thingie to place include-files at one
single place - think of renamed or moved (uapi) include-files.
Looking at xhci-ring.c means for me to dig through 3 or 4 files as
someone not dealing everyday with USB stuff.

What is the effect of CONFIG_DYNAMIC_DEBUG=[y|n] in the affected code?
