From 7af35b0addbc6b8573e11106dfd3e21adf38f405 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 5 Oct 2017 15:57:51 +0300 Subject: drm/kirin: Checking for IS_ERR() instead of NULL The of_graph_get_remote_node() function doesn't return error pointers, it returns NULL on error so I've updated the check.
