(This commit should go into mainline in 5.8.)
USB gadget subsystem uses the following naming convention for UDC
endpoints:
- "ep-a" names for fully configurable endpoints (address, direction and
transfer type can be changed);
- "ep1in", "ep12out-bulk" names for fixed function endpoints (fixed
address, direction and/or transfer type).
Dummy UDC endpoints are capable of full configuration, but named using
the second scheme.
This patch changes the names of generic Dummy UDC endpoints to "ep-aout",
"ep-bin", etc., to advertise that they have configurable addresses and
transfer types (except that Dummy UDC doesn't support ISO transfers), but
fixed direction.
This is required for Raw Gadget (and perhaps for some other drivers),
that reasons about whether an endpoint has configurable address based
on its name.

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.
