6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx>
commit b8423a2f5814dbf055ed7c41f25bfe91c2066cbe upstream.
If drm_dp_hpd_bridge_register() fails, the probe function returns
without removing the fwnode via fwnode_handle_put(), leaking the
resource.
Jump to fwnode_remove if drm_dp_hpd_bridge_register() fails to remove
the fwnode acquired with device_get_named_child_node().
