ASoC: SOF: topology: Fix memory leak in sof_control_load()
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; Signed-off-by: Yu Liao <liaoyu15@huawei.com> Link: https://lore.kernel.org/r/20220318021616.2599630-1-liaoyu15@huawei.com Signed-off-by: Mark Brown <broonie@kernel.org>
