Commit a59a27176914 ("drm/bridge: tc358767: convert to devm_drm_bridge_alloc() API") split tc_probe_bridge_endpoint() in two functions, thus duplicating the loop over the endpoints in each of those functions. However it missed duplicating the of_graph_parse_endpoint() call which initializes the struct of_endpoint, resulting in an uninitialized read.Fixes: a59a27176914 ("drm/bridge: tc358767: convert to devm_drm_bridge_alloc() API") Reported-by: Colin King (gmail) <[email protected]> Closes: https://lore.kernel.org/all/056b34c3-c1ea-4b8c-9672-c98903ffd012@[email protected] Signed-off-by: Luca Ceresoli <[email protected]> --- drivers/gpu/drm/bridge/tc358767.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/bridge/tc358767.c b/drivers/gpu/drm/bridge/tc358767.c index 61559467e2d22b4b1b4223c97766ca3bf58908fd..562fea47b3ecf360e64a414e95ab5d645e610e9e 100644 --- a/drivers/gpu/drm/bridge/tc358767.c +++ b/drivers/gpu/drm/bridge/tc358767.c @@ -2422,6 +2422,7 @@ static int tc_probe_bridge_endpoint(struct tc_data *tc, enum tc_mode mode) struct device_node *node = NULL;for_each_endpoint_of_node(dev->of_node, node) {+ of_graph_parse_endpoint(node, &endpoint); if (endpoint.port == 2) { of_property_read_u8_array(node, "toshiba,pre-emphasis", tc->pre_emphasis, --- base-commit: b4cd18f485687a2061ee7a0ce6833851fc4438da change-id: 20250703-drm-bridge-alloc-fix-tc358767-regression-536ea2861af6 Best regards,
