From 747472bb960e37080e0f498f7cf752a89ad148c9 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 11 Sep 2015 00:53:51 -0300 Subject: [PATCH] nitrogen6x: Fix the error handling in board_eth_init() We should not return 0 on failure, so return a negative error code instead. Also centralize the error path so that is easier to follow.
