* the video frame after the end of VBLANK will start scanning out,
* the time immmediately after end of the VBLANK interval. If the
* @crtc is currently inside VBLANK, this will be a time in the future.

* \param dev dev DRM device handle.
* \param crtc crtc for which timestamp should be returned.
* \param *max_error Maximum allowable timestamp error in nanoseconds.
* Implementation should strive to provide timestamp
* with an error of at most *max_error nanoseconds.
* Returns true upper bound on error for timestamp.
* \param *vblank_time Target location for returned vblank timestamp.
* \param flags 0 = Defaults, no special treatment needed.
* \param DRM_CALLED_FROM_VBLIRQ = Function is called from vblank
* irq handler. Some drivers need to apply some workarounds
* for gpu-specific vblank irq quirks if flag is set.
*
* \returns
* Zero if timestamping isn't supported in current display mode or a
