The csc/scaler device pointer (imxmd->m2m_vdev) is assigned after the imx media device v4l2-async probe completes, therefore we need to check if the device is non-NULL before trying to unregister it. This can be the case if the non-completed imx media device is unbinded (or the driver is removed), leading to a kernel oops.
