ASoC: mini2440: Fix uda134x codec problem.
Browse files Browse the repository at this point in the history
ASoC audio for mini2440 platform in current kenrel doesn't work.
First problem is samsung_asoc_dma device is missing in initialization.
Next problem is with codec. Codec is initialized but never probed
because no platform_device exist for codec driver. It leads to errors
during codec binding to asoc dai. Next problem was platform data which
was passed from board to asoc main driver but not passed to codec when
called codec_soc_probe().

Following patch should fix issues. But not sure if in correct way.
Please review.
