IMO, One way to do this is adding field 'struct device *dev' to struct
vb2_queue. This field should be filled by a driver prior to calling
vb2_queue_init.

I haven't looked into the details, but that sounds good to me. Do we have use
cases where a queue is allocated before knowing which physical device it will
be used for ?


I don't think so. In case of S5P drivers, vb2_queue_init is called while opening /dev/videoX.

BTW. This struct device may help vb2 to produce logs with more descriptive client annotation.

What happens if such a device is NULL. It would happen for vmalloc allocator used by VIVI?
