From 326b509238171d37402dbe308e154cc234ed1960 Mon Sep 17 00:00:00 2001 From: Amadeusz Sławiński Date: Wed, 15 Apr 2020 12:28:49 -0400 Subject: ASoC: codecs: hdac_hdmi: Fix incorrect use of list_for_each_entry MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If we don't find any pcm, pcm will point at address at an offset from the the list head and not a meaningful structure. Fix this by returning correct pcm if found and NULL if not. Found with coccinelle.
