Subject: utils_cmd_{get,put}val.c: Fixed usage of parse_identifier().
X-Git-Tag: collectd-4.3.2~6
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=4a005f01e9ba4322bdb41631928ecc9edf51b189;p=collectd.git

utils_cmd_{get,put}val.c: Fixed usage of parse_identifier().

This function modifies its first argument which, in these cases, is used
again after the function call. Now, a copy of the string is passed to
parse_identifier().

This is a backport of 0a905cbd3151716c5749b5e7c5e439861466804d.
