From a68c6b6cc77b841dc37c17a5d9a7074e26801af5 Mon Sep 17 00:00:00 2001 From: Jaska Uimonen Date: Tue, 8 Oct 2019 11:44:41 -0500 Subject: [PATCH] ASoC: SOF: enable dual control for pga Currently sof pga element supports only 1 kcontrol and you can't create for example a mixer element with combined volume slider and mute switch. So enable sof pga to have more than 1 kcontrol associated with it. Also check for possible NULL tlv pointer as switch element might not have it.
