[Bug 2085410] Re: Fix USB device suspend failure while HCD in S4 wakeup

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1007.7
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-
noble-linux-oem-6.11'. If the problem still exists, change the tag
'verification-needed-noble-linux-oem-6.11' to 'verification-failed-
noble-linux-oem-6.11'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
[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-duanchenghao@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. Should be low risk
