Subject: [PATCH] of_net: fix of_get_mac_address retval if compiled without
CONFIG_OF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
of_get_mac_address prior to commit d01f449c008a ("of_net: add NVMEM
support to of_get_mac_address") could return only valid pointer or NULL,
after this change it could return only valid pointer or ERR_PTR encoded
error value, but I've forget to change the return value of
of_get_mac_address in case where the kernel is compiled without
CONFIG_OF, so I'm doing so now.
