Subject: [PATCH v4 09/10] ARM: Kirkwood: support of_get_mac_address new ERR_PTR error
Date:   Fri,  3 May 2019 16:27:14 +0200

Precedence: bulk

There was NVMEM support added to of_get_mac_address, so it could now return
ERR_PTR encoded error values, so we need to adjust all current users of
of_get_mac_address to this new fact.
