From b85008b7020ce00fbf9a36ae56285216fc37737a Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Thu, 18 Oct 2012 11:01:10 +0000 Subject: net/at91_ether/macb: absorb at91_private in to macb private struct This will make it easier to share code between the drivers and eventually merge them into one driver.
