Hi Sakari, I encountered a problem when using async sub-notifiers. It's like that: There are two notifiers, and they are waiting for one subdev. When this subdev is probing, only one notifier is completed and the other one is skipped. I found that in v15 of patch "v4l: async: Allow binding notifiers to sub-devices", "v4l2_async_notifier_complete" is replaced by v4l2_async_notifier_call_complete, which make it only complete one notifier. Why is it changed? Can this be fixed?
