Subject: PCI: ignore pre-1.1 ASPM quirking when ASPM is disabled
From: Matthew Garrett <[email protected]>
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.
