BugLink: https://bugs.launchpad.net/bugs/1805344 Chnangelog: V2: Add BugLink. [Impact] On some thinkpad laptops, Realtek USB3.0 Card Reader [0bda:0328] reports wrong port status on Cannon lake PCH USB3.1 xHCI [8086:a36d] after resume from S3, then kernel hang. [Fix] Restrict the USB2 resume status check in USB2 roothub to fix hang issue. [Test Case] Suspend/resume 30 times OK. [Regression Potential] Low, upstream fix backported/cherry-picked. These 2 patches are already Cc: stable@vger.kernel.org, cosmic and future kernel will get these 2 patches.
