From a8e6d950cdc1012aede8a84d85f902a53d895174 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 24 Jul 2019 14:06:54 +0200 Subject: xen/arm: use dev_is_dma_coherent Use the dma-noncoherent dev_is_dma_coherent helper instead of the home grown variant. Note that both are always initialized to the same value in arch_setup_dma_ops.
