From 6b6a42780597028135f82c96e42c6d2bcd83fbae Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 14 Aug 2015 12:54:36 -0300 Subject: [media] media: use media_gobj inside links Just like entities and pads, links also need to have unique Object IDs along a given media controller. So, let's add a media_gobj inside it and initialize the object then a new link is created.
