From e2df38d868324f2a767d2109cdd8727acb866ca2 Mon Sep 17 00:00:00 2001 From: Berthold Stoeger Date: Tue, 5 Mar 2019 22:58:47 +0100 Subject: Dive site: add dive site ref-counting Instead of setting dive->dive_site directly, call the add_dive_to_dive_site() and unregister_dive_from_dive_site() functions. In the parser this turned out to be a bit tricky.
