From bfab2aacccfc144e2cceccb71ec89f1eff1b8c51 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 14 Aug 2015 12:47:48 -0300 Subject: [media] media: use media_gobj inside entities As entities are graph objects, let's embed media_gobj on it. That ensures an unique ID for entities that can be global along the entire media controller. For now, we'll keep the already existing entity ID. Such field need to be dropped at some point, but for now, let's not do this, to avoid needing to review all drivers and the userspace apps.
