From 08f49200513ca7e42c24ab6f43233ae0a7b8b190 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 11 Feb 2016 17:31:48 -0200 Subject: [PATCH] [media] cx231xx: use v4l2 core function to create the MC graph Instead of having its own routine, use the one defined at the core, as it is generic enough to handle the cx231xx usecases.
