ASoC: qcom: Fix NULL Dereference in asoc_qcom_lpass_cpu_platform_probe()

Browse source

commit 49da1463c9 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.
