ASoC: qcom: Fix NULL Dereference in asoc_qcom_lpass_cpu_platform_probe()
commit 49da1463c9e3d2082276c3e0e2a8b65a88711cd2 upstream.
A devm_kzalloc() in asoc_qcom_lpass_cpu_platform_probe() could
possibly return NULL pointer. NULL Pointer Dereference may be
triggerred without addtional check.
Add a NULL check for the returned pointer.
