[alsa-devel] [PATCH] ASoC: Fix wrong define for AD1836_ADC_WORD_OFFSET

[Axel Lin]

According to the datasheet:
The BIT[5:4] of ADC Control Register 2 is to control the word width.
        00 = 25 Bits
        01 = 20 Bits
        10 = 16 Bits
        11 = Invalid

Thus, the AD1836_ADC_WORD_OFFSET should be defined as 4.
