Drop the bogus endpoint-lookup helper which could end up accepting interfaces based on endpoints belonging to unrelated altsettings. Note that the returned bulk pipes and interrupt endpoint descriptor were never actually used. Instead the bulk-endpoint numbers are hardcoded to 1 and 2 (matching the specification), while the interrupt- endpoint descriptor was assumed to be the third descriptor created by USB core. Try to bring some order to this by dropping the bogus lookup helper and adding the missing endpoint sanity checks while keeping the interrupt- descriptor assumption for now.

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.
