From 8edfe3b6fad28da191c8fa15e4e0d8f7335a0091 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Sat, 7 Mar 2015 12:10:26 +0100 Subject: bgmac: Clean warning messages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On my test environment the throughput of a file transfer drops from 4.4MBps to 116KBps due the number of repeated warning messages. This patch removes the warning messages as DMA works correctly with addresses using 0xC0000000 bits. Signed-off-by: Peter Senna Tschudin Acked-by: Rafał Miłecki Signed-off-by: David S.
