Subject: Re: [RFT 09/25] ARM: dts: s5pv210: fix number of I2S DAI cells

Sadly, this is causing issues for me.  The machine driver is no longer probing correctly
on the Galaxy S.

The failing call in sound/soc/samsung/aries_wm8994.c is

	/* Set CPU of_node for BT DAI */
	aries_dai[2].cpus->of_node = of_parse_phandle(cpu,
			"sound-dai", 1);

where cpus->of_node is not set properly.  Which is definitely weird because it doesn't
look like this should affect that.

Let me know if there's any specific test that you want me to do.

Thanks,
Jonathan
