From c04efbfd76d23157e64e6d6147518c187ab4233a Mon Sep 17 00:00:00 2001 From: Chen Ni Date: Fri, 15 Sep 2023 02:13:44 +0000 Subject: ASoC: hdaudio.c: Add missing check for devm_kstrdup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Because of the potential failure of the devm_kstrdup(), the dl[i].codecs->name could be NULL. Therefore, we need to check it and return -ENOMEM in order to transfer the error.
