3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Anders Roxell <anders.rox...@linaro.org>

commit 8a7e2d2ea080d10a189a1d611344b0330468ebc3 upstream.

The strncpy doesn't null terminate the string because the size is too
short by one byte.

parse.c: In function ‘prepare_default_config’:
parse.c:148:2: warning: ‘strncpy’ output truncated before terminating
    nul copying 8 bytes from a string of the same length
    [-Wstringop-truncation]
  strncpy(config->governor, "ondemand", 8);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The normal method of passing the length of the destination buffer works
correctly here.

Fixes: 7fe2f6399a84 ("cpupowerutils - cpufrequtils extended with quite some 
features")
