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. Fixes: 86418f90a4c1 ("drm: convert drivers to use of_graph_get_remote_node") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20171005125751.jvtjms62vbtxuvak@mwanda
