[Impact]
Test the proposed 5.14 oem kernel, and get a failure symptom.
Unplug a usb drive from WD19TB docking and a BUG reported in kernel,
then the other embedded usb port can't detect usb drive anymore after
a while.
kernel: usb 5-2.3.3: USB disconnect, device number 5
kernel: BUG: kernel NULL pointer dereference, address: 0000000000000030
kernel: #PF: supervisor read access in kernel mode
kernel: #PF: error_code(0x0000) - not-present page
kernel: PGD 0 P4D 0
kernel: Oops: 0000 [#1] SMP NOPTI
