In etdm dai driver, dai_etdm_parse_of() function is used to parse dts properties to get parameters. There are two for-loops which are sepearately for all etdm and etdm input only cases. In etdm in only loop, dai_id is not initialized, so it keeps the value intiliazed in another loop.
In the patch, add the missing initialization to fix the unexpected parsing problem.
