[media] v4l: vb2-dma-contig: fail if user ptr buffer is not correctly aligned
The DMA transfer must be aligned to a specific value. If userptr is not aligned
to DMA requirements then unexpected corruptions of the memory may occur before
or after a buffer. To prevent such situations, all unligned userptr buffers
are rejected at VIDIOC_QBUF.
