Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: arm):
drivers/usb/host/ohci-tmio.c: In function ‘tmio_stop_hc’:
./include/linux/device.h:1499:2: warning: this statement may fall through [-Wimplicit-fallthrough=]

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.
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.
