From de39078779cb08b21e7e3d2daa7d3b64a53a8d20 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 5 Feb 2016 07:08:25 -0200 Subject: [PATCH] [media] em2xx: use v4l2_mc_create_media_graph() Now that the core has a function to create the media graph, we can get rid of the specialized code at em28xx.
