CVE-2026-89734

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.
