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

From: Vijendar Mukunda Vijendar.Mukunda@amd.com
commit 4d87ae7508cb7ff58fd0bcecc6e9491f42f987f8 upstream.
Initialize current_be_id to 0 in AMD legacy stack(NO DSP enabled) SoundWire generic machine driver code 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.
