sgtl5000 module install fails during instantiation for i.MX53 QSB

Hi,

On insmod'ing alsa modules for i.MX53 QSB, I get the following error:

root@freescale-qsb:/lib/modules/2.6.38.8+# modprobe snd-soc-sgtl5000
snd_soc_instantiate_card:Entry

asoc: failed to probe codec sgtl5000.1-000a
asoc: failed to instantiate card sgtl5000-audio: -19

On adding more printks, I realize that "_regulator_get" function is
failing(not able to find supply VDDA).

The statically built module gives no such errors. Can someone give some
info on this?
