Hi,
I believe there is a regression in linux-next caused by the following
commit:
commit a59a271769149f0b8258507276f3d2a24370cbdb

drm/bridge: tc358767: convert to devm_drm_bridge_alloc() API
the issue is as follows:
static int tc_probe_bridge_endpoint(struct tc_data *tc, enum tc_mode mode)
{
struct device *dev = tc->dev;
struct of_endpoint endpoint;
struct device_node *node = NULL;
for_each_endpoint_of_node(dev->of_node, node) {
if (endpoint.port == 2) {
...
...
The check for endpoint.port == 2 is checking an uninitialized field in
the uninitialized structure endpoint. The code before this commit called
of_graph_parse_endpoint(node, &endpoint) to fetch endpoint and now
this seems to be missing.
