Subject: [PATCH v1 00/19] Fix dma_map_sg error check

Hi, all,

While working on a bugfix on RTRS[1], I noticed there are quite a few other
drivers have the same problem, due to the fact dma_map_sg return 0 on error,
not like most of the cases, return negative value for error.

I "grep -A 5 dma_map_sg' in kernel tree, and audit/fix the one I feel is buggy,
hence this serry. All the patch are independent, so can go either through the
maintainer tree once it is reviewed.

Thanks!
