usb: misc: fix improper handling of refcount in uss720_probe()
commit 0a96fa640dc928da9eaa46a22c46521b037b78ad upstream.
usb_put_dev shouldn't be called when uss720_probe succeeds because of
priv->usbdev. At the same time, priv->usbdev shouldn't be set to NULL
before destroy_priv in uss720_disconnect because usb_put_dev is in
destroy_priv.
Fix this by moving priv->usbdev = NULL after usb_put_dev.
