Subject: core: fix line-info strings termination
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5533f277aa28b36f8ed4bbfac8e22e011ed68858;p=qemu-gpiodev%2Flibgpiod.git

core: fix line-info strings termination

strncpy() truncates the destination buffer if it isn't large enough to
hold the copy. Thus, let's increase the size of the destination strings
to add the NULL character at the end.
