[PATCH 4/9] arm64: dma-mapping: export symbol arch_setup_dma_ops

From: Jim Quinlan
Date: Wed Oct 11 2017 - 18:35:12 EST


The BrcmSTB driver needs to get ahold of a pointer to swiotlb_dma_ops.
However, that variable is defined as static. Instead, we use
arch_setup_dma_ops() to get the pointer to swiotlb_dma_ops. Since
we also want our driver to be a separate module, we need to
export this function.
