Dear Peter,

On OMAP4 we have one interrupt line per McBSP port. At proble time tx, and rx irq value will be -ENXIO,
s/proble/probe/
and only the tx irq will get corrected. In omap_mcbsp_request if the rx_irq is not 0 we proceed, and try to request the interrupt, which will fail on OMAP4 (rx_irq == -6). To avoid this error, clear the rx_irq at probe time on OMAP4.
