[PATCH RFT] ASoC: sgtl5000: Fix up define for SGTL5000_SMALL_POP

[Axel Lin]

Currently, below code actually does not update any bit because
SGTL5000_SMALL_POP is 0.

snd_soc_update_bits(codec, SGTL5000_CHIP_REF_CTRL, SGTL5000_SMALL_POP, 1);

The SGTL5000_SMALL_POP should be BIT(0) rather than 0, fix it.

Hi,
I don't have h/w and datasheet, but the code looks obvious does not make
sense. Can someone help to confirm and test if this patch?
Thanks,
Axel

I can not test this right now, but it seems appropriate.

The datasheet can be found online: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=SGTL5000&fpsp=1&tab=Documentation_Tab

I just checked the datasheet and confirm the SMALL_POP is BIT(0).

Thanks for your report, seems your are right. I have no board to test it.

The code introduced by c251ea7bd7a04f1f2575467e0de76e803cf59149.
Fabio, can you verify it on mx28evk?

Thanks
