dmaengine: use kmem_cache_zalloc instead of kmem_cache_alloc/memset
Using kmem_cache_zalloc() instead of kmem_cache_alloc() and memset(). spatch with a semantic match is used to found this problem. (http://coccinelle.lip6.fr/) Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
