When creating a device path in the driver the snprintf() takes up to 16 characters long argument along with the additional up to 12 characters for the signed integer (as it can't see the actual limits) and tries to pack this into 16 bytes array. GCC complains about that when build with `make W=1`: drivers/usb/core/usb.c:705:25: note: ‘snprintf’ output between 3 and 28 bytes into a destination of size 16 Since everything works until now, let's just check for the potential buffer overflow and bail out. It is most likely a never happen situation, but at least it makes GCC happy.

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.
