From 7d3540104ba156ddc2a80f5c9608958faad01cec Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/42] PCI: ignore pre-1.1 ASPM quirking when ASPM is
disabled
commit 4949be16822e92a18ea0cc1616319926628092ee upstream.
Right now we won't touch ASPM state if ASPM is disabled, except in the case
where we find a device that appears to be too old to reliably support ASPM.
Right now we'll clear it in that case, which is almost certainly the wrong
thing to do. The easiest way around this is just to disable the blacklisting
when ASPM is disabled.
