Subject: [PATCH 25/28] ARM: davinci: remove dead code related to MAC address reading
Date:   Wed,  8 Aug 2018 17:31:47 +0200
Message-Id: <20180808153150.23444-26-brgl@bgdev.pl>
In-Reply-To: <20180808153150.23444-1-brgl@bgdev.pl>
References: <20180808153150.23444-1-brgl@bgdev.pl>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

There are no more users of davinci_get_mac_addr(). Remove it. Also
remove the mac_addr field from the emac platform data struct.
