commit b6313899f4ed2e76b8375cf8069556f5b94fbff0 upstream.
Since we make sure the destination buffer has at least strlen(orig) + 1,
no need to do a strncpy(dest, orig, strlen(orig)), just use strcpy(dest,
orig).
This silences this gcc 8.2 warning on Alpine Linux:
In function 'add_man_viewer',
inlined from 'perf_help_config' at builtin-help.c:284:3:
builtin-help.c:192:2: error: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]
strncpy((*p)->name, name, len);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
builtin-help.c: In function 'perf_help_config':
builtin-help.c:187:15: note: length computed here
size_t len = strlen(name);
^~~~~~~~~~~~

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
