From b34163bf9967a2794bda41fc651fd1e1c6688db4 Mon Sep 17 00:00:00 2001 From: Jakob Koschel Date: Mon, 21 Mar 2022 13:36:26 +0100 Subject: [PATCH] staging: greybus: codecs: fix type confusion of list iterator variable [ Upstream commit 84ef256550196bc06e6849a34224c998b45bd557 ] If the list does not exit early then data == NULL and 'module' does not point to a valid list element. Using 'module' in such a case is not valid and was therefore removed.
