Bluetooth: btusb: fix use-after-free on marvell probe failure
Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: fix use-after-free on marvell probe failure Make sure to stop any TX URBs submitted during Marvell OOB wakeup configuration on later probe failures to avoid use-after-free in the completion callback. This issue was reported by Sashiko while reviewing a fix for a wakeup source leak in the btusb probe errors paths.
