Subject: crypto: caam/qi - explicitly set dma_ops
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since ARM64 commit 1dccb598df549 ("arm64: simplify dma_get_ops"),
dma_ops no longer default to swiotlb_dma_ops, but to dummy_dma_ops.

We have to explicitly set dma_ops in the driver - at least for ARM64.

Fixes: 67c2315def06 ("crypto: caam - add Queue Interface (QI) backend support")
