watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init code
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove to fail because of an incorrect usage count. The probe for this driver does a for_each_pci_dev() which gets a reference for a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop puts a reference for a pci_dev when iTCO_wdt_init() fails, so the iTCO_wdt_init() does not need to do any pci_dev_put()'s. The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
