Subject: [PATCH 3.19.y-ckt 60/86] ASoC: pxa: pxa2xx-ac97: fix dma requestor lines

3.19.8-ckt9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Robert Jarzmik <robert.jarzmik@...e.fr>

commit 8811191fdf7ed02ee07cb8469428158572d355a2 upstream.

PCM receive and transmit DMA requestor lines were reverted, breaking the
PCM playback interface for PXA platforms using the sound/soc/ variant
instead of the sound/arm variant.

The commit below shows the inversion in the requestor lines.
