Hi, as Im using yocto to construct the dsplink, there is already a fix for
this mismatch, there is a patch made by Enric Balletbo in the meta-ti layer
which modify the irq for newer kernels.

I incorporate this to my yocto recipes and the messagegpp and the ringio
examples are working. Hope this could help you.
