Bug description:
[Impact]
Process of s3 resume take 7s and it's too long which is over 5s.
[Fix]
the commit is from
https://lore.kernel.org/linux-pci/[email protected]/
Reference link_active_reporting field of PCI device to determine whether
delay is taken or not.
Actual delay would be determined by taking maximum between 100ms and pci
device's d3cold delay.
[test]
With the patch, the total time s3 resume is 3874.298 ms which is smaller than
5s.
[Regression Potential]
Medium. This patch only changes the rules to determine whether delay is taken
or not.
Reference the right field(link_active_reporting), but not speed of pci device.
