PCIe hotplug bridges are always either Root Ports or Downstream Ports. No other device type can have a PCIe link leading downstream to a slot. Root Ports don't have an upstream bridge, so "dev->is_hotplug_bridge && dev->bus->self" is true if and only if "dev" is a Downstream Port. That means we can simplify this by looking at the type of "dev" itself, without looking upstream at all. No functional change.
