Arnd Bergmann 54333dcc9d usb: mtu3: fix EXTCON dependency
commit 3d54d10c6a upstream.

When EXTCON is a loadable module, mtu3 fails to link as built-in:

drivers/usb/mtu3/mtu3_plat.o: In function `mtu3_probe':
mtu3_plat.c:(.text+0x690): undefined reference to `extcon_get_edev_by_phandle'

Add a Kconfig dependency to force mtu3 also to be a loadable module
if extconn is, but still allow it to be built without extcon.

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
