Subject[media] videobuf-dma-contig: fix vm_iomap_memory() call
Hi all,

This is a trivial fix, but I think the patch itself has problem too.
The function requires a phys_addr_t, but we feed it with a dma_handle_t.
AFAIK, this implicit conversion does not always work.
Can I use virt_to_phys(mem->vaddr) to get the physical address instead?
(mem->vaddr and mem->dma_handle are from dma_alloc_coherent)
