Subject: [PATCH 4.4 111/117] crypto: marvell/cesa - fix test in mv_cesa_dev_dma_init()

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris BREZILLON <boris.brezillon@...e-electrons.com>

commit 8a3978ad55fb4c0564d285fb2f6cdee2313fce01 upstream.

We are checking twice if dma->cache_pool is not NULL but are never testing
dma->padding_pool value.
