Official description

In the Linux kernel, the following vulnerability has been resolved: gpio: amd8111: Fix PCI device reference count leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL input parameter, there is no problem for the 'Device not found' branch. For the normal path, add pci_dev_put() in amd_gpio_exit().
