From d0f1d5ae23803bd82647a337fa508fa8615defc5 Mon Sep 17 00:00:00 2001 From: Evgeny Novikov <novikov@ispras.ru> Date: Fri, 30 Jul 2021 19:51:08 +0300 Subject: HID: thrustmaster: Fix memory leaks in probe When thrustmaster_probe() handles errors of usb_submit_urb() it does not free allocated resources and fails. The patch fixes that. Found by Linux Driver Verification project (linuxtesting.org).
