Description
In the Linux kernel, the following vulnerability has been resolved:
rapidio: devices: fix missing put_device in mport_cdev_open
When kfifo_alloc fails, the refcount of chdev->dev is left incremental. We should use put_device(&chdev->dev) to decrease the ref count of chdev->dev to avoid refcount leak.
