Subject: [PATCH RFT] regulator: ab8500: Fix voltage_shift setting for AB8540_LDO_DMIC

The voltage_mask is 0xc0, thus we need to set voltage_shift = 6 to get correct
selector in get_voltage_sel and set_voltage_sel.

Hi Bengt,
I don't have the datasheet. Can you confirm if this fix is correct?

BTW, can you also review a couple patches for ab8500 and ab8500-ext I sent a few
days ago? I ask this because now I have more patches that may depend on previous
patches.

Thanks,
Axel

The patch is correct. Voltage selection is done with 0xc0.

Applied, thanks.
