Registering real device entries (struct device) for the mode muxes as well as for the orientation switches. The Type-C mux code was deliberately attempting to avoid creation of separate device entries for the orientation switch and the mode switch (alternate modes) because they are not physical devices. They are functions of a single physical multiplexer/demultiplexer switch device. Unfortunately because of the dependency we still have on the underlying mux device driver, we had to put in hacks like the one in the commit3e3b81965c("usb: typec: mux: Take care of driver module reference counting") to make sure the driver does not disappear from underneath us. Even with those hacks we were still left with a potential NUll pointer dereference scenario, so just creating the device entries, and letting the core take care of the dependencies. No more hacks needed.

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.
