Tingwei Zhang da012618c5 coresight: etm: perf: Fix warning caused by etm_setup_aux failure ... [ Upstream commit 716f5652a1 ] When coresight_build_path() fails on all the cpus, etm_setup_aux calls etm_free_aux() to free allocated event_data. WARN_ON(cpumask_empty(mask) will be triggered since cpu mask is empty. Check event_data->snk_config is not NULL first to avoid this warning.
