Summary
In the Linux kernel, the following vulnerability has been resolved:
media: radio-keene: fix memory leak in error path
Fix a memory leak in usb_keene_probe(). The v4l2 control handler is
initialized and controls are added, but if v4l2_device_register() or
video_register_device() fails afterward, the handler was never freed,
leaking memory.
Add v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure
the control handler is properly freed for all error paths after it is
initialized.
