Subject: crypto: marvell/cesa - fix missing cpu_to_le32() in mv_cesa_dma_add_op()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ea1f662bde067563328ec3083884aaffb3d902d8;p=linux-beck.git

crypto: marvell/cesa - fix missing cpu_to_le32() in mv_cesa_dma_add_op()

When tdma->src is freed in mv_cesa_dma_cleanup(), we convert the DMA
address from a little-endian value prior to calling dma_pool_free().
However, mv_cesa_dma_add_op() assigns tdma->src without first converting
the DMA address to little endian.  Fix this.
