[alsa-devel] [PATCH 6/6] ASoC: jz4740: Improve build test coverage

[Lars-Peter Clausen]

Allow the jz4740 audio drivers to be build when CONFIG_COMPILE_TEST is selected.
This should improve the build test coverage. There is one small piece of
platform dependent code in the jz4740-i2s driver. It uses the DMA request type
constants which are defined in a platform specific header. We can solve this by
moving them from the platform specific header to the I2S driver.

Signed-off-by: Lars-Peter Clausen <lars at metafoo.de>

Preferably this should go through the ASoC tree, but needs an Ack from Ralf for
the MIPS portions.
