Subject: [PATCH v3 09/18] ARM: davinci: da850-evm: remove dead MTD code
Date: Thu, 28 Jun 2018 16:32:35 +0200	[thread overview]
Message-ID: <20180628143244.4561-10-brgl@bgdev.pl> (raw)
In-Reply-To: <20180628143244.4561-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We no longer need to register the MTD notifier to read the MAC address
as it's now being done in the emac address.
