Public bug reported: [SRU Justification]
[Impact] More and more USB device suspend failure are caused by the un-expected HCD_FLAG_WAKEUP_PENDING on the USB host controller. It mostly happens on the USB devices connected to the high-speed root hub. It randomly happens when put the system into suspend [Fix] Fixed by the upstream fix https://lore.kernel.org/linux-usb/20241012094633.126736-1-duancheng...@kylinos.cn/. Set wakeup to false if suspend type is either PM_EVENT_FREEZE or PM_EVENT_QUIESCE [Test Case] 1. Power on machine and connect a USB device to the high-speed root hub. (Find your device in lsusb in the secondary root hub) 2. run checkbox-cli run com.canonical.certification::suspend-cycles-stress-test 3. observe the suspend/resume fail with the kernel message [Where problems could occur] Add more restriction on how the wakeup should be performed.
