`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect `c2dev->name` to be NUL-terminated based on its usage with format strings: | dev_info(c2dev->dev, "C2 port %s removed\n", c2dev->name); Moreover, NUL-padding is _not_ required as c2dev is zero-allocated: | c2dev = kzalloc(sizeof(struct c2port_device), GFP_KERNEL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Let's also drop `C2PORT_NAME_LEN - 1` for `sizeof(dest)` which is more idiomatic strscpy usage.

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.
