Hi all,

After merging the dma-mapping tree, today's linux-next build (htmldocs)
produced this warning:

kernel/dma/mapping.c:224: warning: Function parameter or member 'nents' not described in 'dma_map_sg_attrs'

Caused by commit

  fffe3cc8c219 ("dma-mapping: allow map_sg() ops to return negative error codes")

Cheers,
