From c8597af855f3e34aaebaff0e5c3dbd07611c87f1 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Tue, 6 Jun 2017 15:45:07 +0100 Subject: ASoC: topology: Allow bespoke configuration post widget creation Current topology only allows for widget configuration before the widget is registered. This patch also allows further configuration and usage after registration is complete.
