Subject: [PATCH] crypto: caam/qi - explicitly set dma_ops
Mime-version: 1.0

Git-commit: 5747ff3091f7328a0c3e63eafedafe80d7953be8
Patch-mainline: v4.14-rc1
References: bsc#1051510
Since ARM64 commit 1dccb598df549 ("arm64: simplify dma_get_ops"),
dma_ops no longer default to swiotlb_dma_ops, but to dummy_dma_ops.
dma_ops have to be explicitly set in the driver - at least for ARM64.
