I double checked this issue.
It seems below 2 things happend in the same time.
Thank you. Your feedback/hint helped it.
Good things is that there is no issue at upstream code.
1) latest ASoC branch had delayed_work update
2) my local patch didn't care about it
Thank you for your help !!
Best regards
