I'm looking for Ack's on patches 4 and 5 from the SPI and ASoC maintainers
respectively, so that I can take this series through the Tegra tree for 3.7.

When this series was first posted, there was a bug in the Tegra ASoC PCM
driver which prevented it from working. A fix for this has since been
applied to ASoC's for-3.6 branch and hence should show up in 3.6.
