Since renesas_usb3 udc driver calls usb_of_get_companion_dev()
which is on usb/core/of.c, build error like below happens if we
disable CONFIG_USB because the usb/core/ needs CONFIG_USB:
ERROR: "usb_of_get_companion_dev" [drivers/usb/gadget/udc/renesas_usb3.ko] undefined!
According to the usb/gadget/Kconfig, "NOTE: Gadget support
** DOES NOT ** depend on host-side CONFIG_USB !!".
So, to fix the issue, this patch changes the usb_of_get_companion_dev()
place from usb/core/of.c to usb/common/common.c to be called by both
host and gadget.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
