I was trying to get audio going through McBSP3, and was getting this:
omap-mcbsp omap-mcbsp.3: Unable to request RX IRQ 0 for McBSP3
This patch fixes the problem for me.
-------------------------------------------------------------------------
From: Grazvydas Ignotas <notasas@xxxxxxxxx>
Transmit and receive interrupts must be specified for McBSP
driver to work with McBSP 3-5.
