From 61eb0add28023119773d6aab8f402e149473920c Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 21 Sep 2022 14:27:51 +0300 Subject: [PATCH] ASoC: SOF: ipc4-topology: Free the ida when IPC fails in sof_ipc4_widget_setup() The allocated ida needs to be freed up if the IPC message fails since next time when we try again to set up the widget we are going to try to allocate another ID and given enough tries, we are going to run out of unique IDs.
