From a52ce121918382a4249d621cceb07c30e1c00fa2 Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Wed, 1 Oct 2014 16:31:50 +0100 Subject: [PATCH] arm64: Use DMA_ERROR_CODE to denote failed allocation This patch replaces the static assignment of ~0 to dma_handle with DMA_ERROR_CODE to be consistent with other platforms.
