Subject: [PATCH -next] ASoC: SOF: topology: Fix memory leak in sof_control_load()
Date: Fri, 18 Mar 2022 10:16:16 +0800 [thread overview]
Message-ID: <20220318021616.2599630-1-liaoyu15@huawei.com> (raw)
scontrol doesn't get freed when kstrdup returns NULL.
Fix by free iscontrol in that case.
scontrol = kzalloc(sizeof(*scontrol), GFP_KERNEL);
if (!scontrol)
return -ENOMEM;
scontrol->name = kstrdup(hdr->name, GFP_KERNEL);
if (!scontrol->name)
return -ENOMEM;
