The user of VB2_USERPTR with vb2_dma_contig_memops makes no sense
since it requires that the user pointer buffer is in contiguous
memory. This was required with old hacks in the past, but these
days we have DMABUF to take that role.

This RFC series drops VB2_USERPTR from any vb2_queue that uses
vb2_dma_contig_memops.

Note that this series depends on a patch that adds VB2_DMABUF
to any driver that didn't have that:

https://patchwork.linuxtv.org/patch/61782/

And for the rkisp1 a patch to remove VB2_USERPTR has already
been posted:

https://patchwork.linuxtv.org/patch/61780/

Regards,
