Appended one more fix, updated diffstat included below for verification
(but it is identical):

    avr32: at32ap700x: fix typo in DMA master configuration
    
    Commit 4aa5f366431fe (avr32: at32ap700x: specify DMA src and dst
    masters) specified the masters for the ac97c playback device
    but incorrectly set them in the capture slave information rather
    than playback.
