dma-mapping: fix the kerneldoc for dma_map_sgtable()
htmldocs began producing the following warnings: kernel/dma/mapping.c:256: WARNING: Definition list ends without a blank line; unexpected unindent. kernel/dma/mapping.c:257: WARNING: Bullet list ends without a blank line; unexpected unindent. Reformatting the list without hyphens fixes the warnings and produces both a readable text and HTML output. Fixes: fffe3cc8c219 ("dma-mapping: allow map_sg() ops to return negative error code") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
