[PATCH v2 3/4] crypto: ux500 - Fix the parameter of dma_unmap_sg()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xiang Chen <chenxiang66@xxxxxxxxxxxxx>

For function dma_unmap_sg(), the <nents> parameter should be number of
elements in the scatterlist prior to the mapping, not after the mapping.
So fix this usage.
