From 6a0a923dfa1480df41fb486323b8375e387d516f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20=C5=A0tetiar?= Date: Sun, 19 May 2019 14:18:44 +0200 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.
