This change is similar to commit a1616a5ac9 ("Bluetooth: hidp: fix
buffer overflow") but for the compat ioctl. We take a string from the
user and forgot to ensure that it's NUL terminated.
I have also changed the strncpy() in to strscpy() in hidp_setup_hid().
The difference is the strncpy() doesn't necessarily NUL terminate the
destination string. Either change would fix the problem but it's nice
to take a belt and suspenders approach and do both.

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.
