PCI: Enable ASPM state clearing regardless of policy
Alex Williamson [Thu, 10 Mar 2011 18:54:16 +0000 (11:54 -0700)]
Commit 2f671e2d allowed us to clear ASPM state when the FADT
tells us it isn't supported, but we don't put this into effect
if the aspm_policy is set to POLICY_POWERSAVE.  Enable the
state to be cleared regardless of policy.
