I don't understand why you aren't giving a full description of the
situation here. You should say something more like this (edit to your
taste):
In ``<uapi/linux/usb/ch9.h>`` you will find the USB data types
defined in chapter 9 of the USB specification. These data types are used
throughout USB, and in APIs including this host side API, gadget APIs,
usb character devices and debugfs interfaces. That file is itself
#include'd by ``<linux/usb/ch9.h>``, which also contains declarations of
a few utility routines for manipulating these data types; the
implementations are in ``drivers/usb/common/common.c``.
.. kernel-doc:: drivers/usb/common/common.c
:export:
In addition, some functions useful for creating debugging output are
defined in ``drivers/usb/common/debug.c``.
