A malformed USB descriptor may pass the lengthy mixer description with a lot of channels, and this may overflow the 32bit integer shift size, as caught by syzbot UBSAN test. Although this won't cause any real trouble, it's better to address. This patch introduces a sanity check of the number of channels to bail out the parsing when too many channels are found.

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 reStructuredText 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.
