ASoC: Intel: avs: Fix null-ptr-deref in avs_component_probe()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
avs_component_probe() does not check for this case, which results in a
NULL pointer dereference.
Fixes: 739c031110da ("ASoC: Intel: avs: Provide support for fallback topology")
