This is not valid kerneldoc comment.  Try something like this:

/**
 * is_downstream_to_pci_bridge - test if a device belongs to the PCI
 *				 sub-hierarchy of a candidate PCI-PCI bridge
 * @dev: candidate PCI device belonging to @bridge PCI sub-hierarchy
 * @bridge: the candidate PCI-PCI bridge
 *
 * Returns true if @dev belongs to @bridge PCI sub-hierarchy, else false.
