[PATCH v2 0/4] Fix the parameter of dma_map_sg()
by chenxiang 26 Mar '21

26 Mar '21

From: Xiang Chen <chenxiang66(a)hisilicon.com> According to Documentation/core-api/dma-api-howto.rst, the parameters of dma_unmap_sg() must be the same as those which are passed in to the scatter/gather mapping API. But for some drivers under crypto, the <nents> parameter of dma_unmap_sg() is number of elements after mapping. So fix them. Part of the document is as follows: To unmap a scatterlist, just call:: dma_unmap_sg(dev, sglist, nents, direction); Again, make sure DMA activity has already finished. .. note:: The 'nents' argument to the dma_unmap_sg call must be the _same_ one you passed into the dma_map_sg call, it should _NOT_ be the 'count' value _returned_ from the dma_map_sg call.
