Re: [PATCH 0/3] aic23 sound driver fixes

["James Selvam" <james.iisc@gmail.com>]

Hi Mika/All,

I have all the relavant nodes created in /dev/snd directory. This includes
controlCx, hwCxDy, midiCxDy, pcmCxDyc, pcmCxDyc, seq & timer.

I have also put the following three lines:

        spin_lock_irqsave(&s->dma_lock, flags);
        omap_stop_alsa_sound_dma(s);
        spin_unlock_irqrestore(&s->dma_lock, flags);

Any ideas about how to get this working? Is there something else missing?

Thanks,
James.
