pata_ali: misplaced pci_dev_put()
The ali_init_one() function does a search for an isa_bridge,
but then fails to release it if the revision information was
not correctly found.
the problem comes from:
isa_bridge = pci_get_device(...);
if (isa_bridge && ...) {
pci_dev_put(isa_bridge);
}
where the pci_dev_put() is never called if isa_bridge
was valid but the extra checks on the chip-revision
fail to match.
