When checking if we need one more packet on a bulk pipe we may, even
though not probable at all, get there with a zero maxpacketsize.
In that case for sure no packet, no even a one more, will be
allocated.
This will clean the clang-analyzer warning:
drivers/usb/isp1760/isp1760-hcd.c:1856:38: warning: Division by zero [clang-analyzer-core.DivideZero]

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.
