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 patchset. As suggested by Christoph Hellwig, I now send the patches per subsystem, this is for crypto subsystem. Thanks!
