Subject: crypto: caam/qi - explicitly set dma_ops
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5747ff3091f7328a0c3e63eafedafe80d7953be8;p=openwrt%2Fstaging%2Fblogic.git

crypto: caam/qi - explicitly set dma_ops

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.

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