Ivan Orlov 015fbddefc USB: make usb class a const structure
Now that the driver core allows for struct class to be in read-only
memory, remove the usb_class structure and create the usbmisc_class
const class structure declared at build time which places it into
read-only memory, instead of having it to be dynamically allocated
at load time.

Additionally, now we register usb class at startup and unregister it
when shutting down, so we don't have to count uses of the class.
Therefore we don't need the 'usb_class' structure anymore. Due to this
fact, remove all static functions related to class initialization and
deinitialization. We can't use them in 'usb.c' since they are static
and we don't really need them anymore.

Since we have to register the class in usb_init function in 'usb.c'
and use it in 'file.c' as well, declare the usbmisc_class structure
as 'export' in the 'usb.h' file.

Debatable moment: the class registration and unregistration functions
could be extracted to the 'file.c'. I think we don't want to do this
since it would be one-line functions. They would make the code paths
more confusing and add calling overhead.

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.
