It's possible that you will receive thousands of interrupt requests
after initialization for 2.0 roothub. And you will get a lot of
warning like, "xHCI dying, ignoring interrupt. Shouldn't IRQs be
disabled?". This amount of interrupt requests will cause the entire
system to freeze.
This problem was first found on a device with ASM2142 host controller
on it.

the test robot did not find this original problem, it only found
problems with your original submission, which is different.
"Reported-by" shouldn't had been put here.
Quote from the last email test robot sent to me，
"If you fix the issue, kindly add following tag where applicable

Where should I put this? Or just ignore it?
