Subject: [PATCH v2 0/2] hwrng: 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 amd-hwrng and geode-hwrng.


ChangeLog:
v1 -> v2:
  1. fix error in amd_rng_mod_exit()
  2. also add refcount leak fix for geode-hwrng

Xiongfeng Wang (2):
  hwrng: amd - Fix PCI device refcount leak
  hwrng: geode - Fix PCI device refcount leak
