The init_cfg callback is intended for initialising the format configuration
(as well as compose and crop where relevant) to the device default values.
The implementation in e.g. drivers/media/i2c/ov7251.c seems abour right,
for instance.
I think this would be relevant in addressing the compile issues without
subdev uAPI, too.
I've postponed the two patches, feel free to send either delta or v7 of
this.
