commit bedf8bcf6b4f90a6e31add3721a2e71877289381 introduced reference counting for struct v4l2_device. In v4l2_device_register() a call to kref_init() initializes reference count to 1, but in v4l2_device_unregister() there is no corresponding decrement. End result is that reference count never reaches zero and v4l2_device_release() is never called, not even on videodev module unload. Fix this by adding reference counter decrement to v4l2_device_unregister(). Resending due to spurious newlines around the patch in previous message.
