    Subject[PATCH] [109/223] ASoC: wm8961 - clear WM8961_MCLKDIV bit for freq <= 16500000
    Date
    2.6.35-longterm review patch.  If anyone has any objections, please let me know.

    ------------------
    From: Axel Lin <axel.lin@gmail.com>

    commit 2f7dceeda4708f470fd927adb3861bd8ebbe2310 upstream.

    MCLKDIV bit of Register 04h Clocking1:
    0 : Divide by 1
    1 : Divide by 2

    Thus in the case of freq <= 16500000, we should clear MCLKDIV bit.
