According to Documentation/DMA-API.txt, all the parameters of dma_unmap_sg()
must be the same as those and passed in to the scatter/gather mapping API.
But in scsi drivers such as ibmscsi_tgt/iscsi/mvsas/pm8001, the <nents>
parameter of dma_unmap_sg() is number of elements after mapping. So fix them.
Part of the document is as follows:
void
dma_unmap_sg(struct device *dev, struct scatterlist *sg,
int nents, enum dma_data_direction direction)
Unmap the previously mapped scatter/gather list. All the parameters
must be the same as those and passed in to the scatter/gather mapping
API.
Note: <nents> must be the number you passed in, *not* the number of
DMA address entries returned.
Chang Log:
v1 -> v2:
