X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0745ee8790ba94f2a2da9af153026455e9b3d98;p=telemetry.git

metrics: Constify the value pointers

Sometimes we will receive some data which has been constified and in
order to pass it on straight away, we will constify the value pointer,
too.
