[alsa-devel] [PATCH v2] ASoC: Intel: fix possible acpi enumeration panic

A crash can occur on some platforms where adsp is enumerated but codec is not matched. Define codec_id as a pointer intead of an array so that it gets initialized to NULL for the terminating element of sst_acpi_bytcr[] and sst_acpi_chv[].
