Description

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uvc: Fix null pointer dereference in uvcg_video_init() In uvcg_video_init(), if kthread_run_worker() fails, the error logged uses uvcg_err(), however, the pointer it uses: video->uvc is not assigned at this point, triggering a null pointer dereference. Fix this by directly using uvc->func which is assigned already.
