crypto: marvell - be explicit about destination in mv_cesa_dma_add_op()
The mv_cesa_dma_add_op() function builds a mv_cesa_tdma_desc structure to copy the operation description to the SRAM, but doesn't explicitly initialize the destination of the copy. It works fine because the operatin description must be copied at the beginning of the SRAM, and the mv_cesa_tdma_desc structure is initialized to zero when allocated. However, it is somewhat confusing to not have a destination defined. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
