PCI / PM: Enforce type casting for pci_power_t

andy-shev · bjorn-helgaas · commit 9661e783d830 · 2016-06-13T10:28:58.000-05:00
When casting variables of type pci_power_t, a static analysis tool complains:

  include/linux/pci.h:119:37: warning: cast from restricted pci_power_t

Enforce type casting to make the static analyzer happy.
