Subject: PCI / PM: Enforce type casting for pci_power_t
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9661e783d830699a65f7d42e4b4a76e6923089eb;p=linux-beck.git

PCI / PM: Enforce type casting for pci_power_t

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.
