From 0ac69de37277aec31d18a8c7b9d9a3a65b629526 Mon Sep 17 00:00:00 2001
From: Yangbo Lu <yangbo.lu@nxp.com>
Date: Wed, 12 Oct 2016 16:30:57 +0800
Subject: [PATCH 144/226] dpaa: call arch_setup_dma_ops before using dma_ops
A previous patch caused dpaa call trace. This patch provides
a temporary workaround for this until this is fixed by upstream.
Fixes: 1dccb598df54 ("arm64: simplify dma_get_ops")
Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
