PCI: Remove unnecessary variable in pci_add_dynid()
The variable "retval" in pci_add_dynid() is only used to store the return value of driver_attach() and is then directly returned. Remove the variable and directly pass on driver_attach()'s return value. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
