For what it's worth, I doubt most of the em28xx designs have the
tvp5150 interrupt request line connected in any way.  You would likely
have to poll the FIFO status register via I2C, or use the feature to
embed the sliced data into as VANC data in the 656 output (as
described in sec 3.9 of the tvp5150am1 spec).
