pata_via: fix double put on isa bridge
In via_init_one, when via_isa_bridges iterator reaches PCI_DEVICE_ID_VIA_ANON and last but one via_isa_bridges bridge is found but rev doesn't match, pci_dev_put(isa) is called twice. Do pci_dev_put only once. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
