V4L/DVB: videobuf: Rename vmalloc fields to vaddr
The videobuf_dmabuf and videobuf_vmalloc_memory fields have a vmalloc field to store the kernel virtual address of vmalloc'ed buffers. Rename the field to vaddr. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
