File 0051-topology-Add-element-ID-so-we-can-look-up-references.patch of Package alsa
From 120b3b8eadd9a2a4c2ede0a246bffa1cfac562a9 Mon Sep 17 00:00:00 2001 From: Jin Yao <yao.jin@linux.intel.com> Date: Tue, 4 Aug 2015 18:09:12 +0100 Subject: [PATCH] topology: Add element ID so we can look up references by name. Add support to lookup elements by name. This is in preparation for adding some new API calls that will allow building topology data using a C API. This will allow applications to build their own topology data directly.
