From 9d6d20e652c0d304f98de30d51805658f98ba27d Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 31 Jul 2018 09:22:40 -0400 Subject: media: v4l2-mc: switch it to use the new approach to setup pipelines Instead of relying on a static map for pids, use the new sig_type "taint" type to setup the pipelines with the same tipe between different entities.
