The purpose of the struct binding image source's async subdev as well as related information is to allow associating the two. This patch breaks that. If your device can support a single sensor, it might not be a big deal. The end result remains somewhat inconsistent as subdev specific information is spread across struct stm32_dcmi and struct dcmi_graph_entity. In general you don't need to know the sensor as you can always find it using media_entity_remote_pad(). This driver is a little different though as it could presumably continue to work without MC. Was that the intent? On a side note: struct dcmi_graph_entity does NOT have struct v4l2_async_subdev as its first member. Please fix that and prepend the fix to this set. -- Kind regards, Sakari Ailus sakari.ailus@xxxxxxxxxxxxxxx
