hwmon: (ibmpowernv) Replace deprecated strncpy() with memcpy()
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. A suitable replacement is `memcpy` as we've already precisely calculated the number of bytes to copy while `buf` has been explicitly zero-initialized: | char buf[8] = { 0 }; Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://manpages.debian.org/testing/linux-manual-4.8/strscpy.9.en.html [2] Link: https://github.com/KSPP/linux/issues/90 Cc: linux-hardening@vger.kernel.org Signed-off-by:Justin Stitt <justinstitt@google.com> Tested-by:
