The comment of\npci_get_device() says that it will increase the reference count for the\nreturned pci_dev and also decrease the reference count for the input\npci_dev @from if it is not NULL.\n\nIf we break for_each_pci_dev() loop with pdev not NULL, we need to call\npci_dev_put() to decrease the reference count. Add the missing\npci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL\ninput parameter, there is no problem for the 'Device not found' branch.\nFor the normal path, add pci_dev_put() in amd_gpio_exit()."
