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.
Change Log: v1 -> v2: Remove changing the count passed to create_sg_component in driver cavium;
