Subject: [PATCH v2 12/25] of: net: kill of_get_nvmem_mac_address()
Date: Tue, 13 Nov 2018 15:01:20 +0100	[thread overview]
Message-ID: <20181113140133.17385-13-brgl@bgdev.pl> (raw)
In-Reply-To: <20181113140133.17385-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We've switched all users to nvmem_get_mac_address(). Remove the now
dead code.
