Damaged Arduino Yun

After a little mishap is my arduino "burned out". The reset circuit was shorted to 15V.
Now is the only function that yun part.
I would like to know what is the blown component and whether a repair is possible.
Unfortunately, I can not find the layout of this board to identify what is this damaged part.

can anyone help me with this?

i made a picture on which the burned component is outlined in red.

@mannibo,
I can't read the part number on my Yun, so I don't know what it is.
You can find the Schematic & Reference Design here
