From 86a5906e4d1df1ec160fa9e18b6f2277a5216c60 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 27 Oct 2015 17:40:26 +0000 Subject: [PATCH] arm64: Fix build with CONFIG_ZONE_DMA=n Trying to build with CONFIG_ZONE_DMA=n leaves visible references to the now-undefined ZONE_DMA, resulting in a syntax error. Hide the references behind an #ifdef instead of using IS_ENABLED.
