Make sure that the interrupt interface has an endpoint before trying to
access its endpoint descriptors to avoid dereferencing a NULL pointer.
The driver binds to the interrupt interface with interface number 0, but
must not assume that this interface or its current alternate setting are
the first entries in the corresponding configuration arrays.

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.
