Re: ASoC: CPU DAI samsung-i2s.0 not registered

[Matt Flax <flatmax@flatmax.org>]

Hi Michael,

I managed to get it to load the driver now with this strange device tree 
related hack I found in the smdk_wm8994 driver ...
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-August/080030.html

But I got a new riddle there as well ... not sure how to register my 
codec now ...

My kernel version is :
Linux version 3.14.0 (flatmax@highAcuity) (gcc version 4.8.2 (GCC) ) #1 
SMP PREEMPT Thu Aug 14 15:47:07 EST 2014
