CVE-2022-49389
usb: usbip: fix a refcount leak in stub_probe()
In the Linux kernel, the following vulnerability has been resolved:
usb: usbip: fix a refcount leak in stub_probe()
usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails
after that, usb_put_dev() needs to be called to release the reference.
Fix this by moving usb_put_dev() to sdev_free error path handling.
Find this by code review.
