From: Qiang Ning <qning0106@xxxxxxx> [ Upstream commit 96da8f148396329ba769246cb8ceaa35f1ddfc48 ] When dln2_setup_rx_urbs() in dln2_probe() fails, error out_free forgets to call usb_put_dev() to decrease the refcount of dln2->usb_dev. Fix this by adding usb_put_dev() in the error handling code of dln2_probe().
