Hi Marek, Pawel, Currently for dma_config (and the dma_sg code that I posted before) drivers have to allocate a alloc_ctx context, but in practice that just contains a device pointer. Is there any reason why we can't just change in struct vb2_queue: void *alloc_ctx[VIDEO_MAX_PLANES]; to: struct device *alloc_ctx[VIDEO_MAX_PLANES]; or possibly even just: struct device *alloc_ctx; That simplifies the code quite a bit and I don't see and need for anything else. The last option would make it impossible to have different allocation contexts for different planes, but that might be something that Samsumg needs.
