From a1d60fe4e9ba46e2f472170e65043f5735af1fd5 Mon Sep 17 00:00:00 2001 From: Niels de Vos Date: Tue, 14 Mar 2017 15:38:39 +0100 Subject: refcount: correct the return value of GF_REF_PUT() It is documented that GF_REF_PUT() returns a 0 in case the call resulted in free'ing the structure. However the implementations did not have a return value, so nothing can actually use it.
