[alsa-devel] How the dma interrupt handlers have been registered in ALSA?

I am referring omap-alsa-dma.c and the related codec files. We usually
register the IRQ handler by calling
request_irq() function but in this mentioned files the IRQ handler etc is
defined but it is not registered anywhere i.e. request_irq is not used
anywhere. Is there any other way of registering irq handlers? The irq
handlers address is passed to
omap_request_dma, but there also it is not registered. I am missing the
entire thing?
