Description

hwrng: amd - Fix PCI device refcount leak

In the Linux kernel, the following vulnerability has been resolved:

hwrng: amd - Fix PCI device refcount 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() for the normal and error path.
