+From d6f6a3e2752f14210dd13b6d3d19bddc13bd9f79 Mon Sep 17 00:00:00 2001
+From: Daniel Matuschek <info@crazy-audio.com>
+Date: Mon, 4 Aug 2014 11:09:58 +0200
+Subject: [PATCH 048/203] Added driver for HiFiBerry Amp amplifier add-on board
+
+The driver contains a low-level hardware driver for the TAS5713 and the
+drivers for the Raspberry Pi I2S subsystem.
+
+TAS5713: return error if initialisation fails
+
+Existing TAS5713 driver logs errors during initialisation, but does not return
+an error code. Therefore even if initialisation fails, the driver will still be
+loaded, but won't work. This patch fixes this. I2C communication error will now
+reported correctly by a non-zero return code.
+
+HiFiBerry Amp: fix device-tree problems
+
+Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.
