From 2ca71b8073831d70c1123a9e950ee0beb16de96f Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Tue, 7 Jul 2020 15:37:46 -0500 Subject: [PATCH] ASoC: topology: fix tlvs in error handling for widget_dmixer commit 8edac489e7c3fce44208373bb3e7b5835a672c66 upstream. we need to free all allocated tlvs, not just the one allocated in the loop before releasing kcontrols - other the tlvs references will leak.
