6.15-stable review patch. If anyone has any objections, please let me know.

From: Vijendar Mukunda Vijendar.Mukunda@amd.com
commit 6b83ba4bc3ecb915476d688c9f00f3be57b49a0c upstream.
Initialize current_be_id to 0 in SOF based AMD generic SoundWire machine driver to handle the unlikely case when there are no devices connected to a DAI. In this case create_sdw_dailink() would return without touching the passed pointer to current_be_id.
