When the system suspend and resume, the USB host will print some errors like can't disable the device under this USB bus and reset-and-verify fails, after that the system can't suspend anymore and hang randomly. [Fix] the mainline build v4.17-rc1 doesn't have this issue, so through bisecting, we found this patch can fix the problem. [Test Case] suspend and resume 30 times, and plug sd storage card into the cardreader, everything worked well. [Regression Potential] Low, we tested this patch on 7 different lenovo laptops. After suspending and resuming for 30 times, the system still worked well, and plug a usb storage, it still worked well.
