- case DEVICE_TYPE_FBDEV:
- /* fbdev devices have no way to synchronize access. Moreover,
- * they mostly operate through mmaps() without any pageflips
- * and modesetting, so there is no way for us to prevent access
- * but tear down mmaps.
- * That would be quite expensive to do on a per-fd context. So
- * ignore legcy fbdev and let its users feel the pain they asked
- * for when deciding for fbdev. */
