Build kernel with SND_SOC_IMC_PCM_DMA=m && SND_IMX_SOC=n leads the following
error:

   sound/built-in.o: In function `fsl_sai_probe':
>> fsl_sai.c:(.text+0x5f662): undefined reference to `imx_pcm_dma_init'
   sound/built-in.o: In function `fsl_esai_probe':
>> fsl_esai.c:(.text+0x6044b): undefined reference to `imx_pcm_dma_init'

Most cpu driver in soc/fsl has use the function 'imx_pcm_dma_init' which is
defined in imx-pcm-dma.c, so need to select SND_SOC_IMX_PCM_DMA, but it depends
on SND_IMX_SOC, if SND_IMX_SOC=n, then SND_SOC_IMX_PCM_DMA will not be
selected.
So remove the dependence of SND_IMX_SOC for SND_SOC_IMX_PCM_DMA.

Those if conditions where just added[1] by Arnd to avoid other build 
failures. So just removing them again makes little sense.

As far as I can see imx_pcm_dma_init() should be stubbed out when 
SND_SOC_IMX_PCM_DMA is not selected. So what's going on here?

Lars-Peter Clausen & Arnd

The purpose of Arnd's patch is same with me, which is to resolve the build
error when SND_SOC_IMX_PCM_DMA=m & SND_SOC_FSL_SSI/SAI/ESAI/SPDIF=y, the
error is "undefined reference to `imx_pcm_dma_init'".
But Arnd's patch didn't involve this situation that SND_IMX_SOC=n &
SND_SOC_IMX_PCM_DMA=m. 

Currently I think out a solution for this issue is to change

select SND_SOC_IMX_PCM_DMA if SND_IMX_SOC != n 

to

depends on SND_SOC_IMX_PCM_DMA != m

How do you think about this?

What will happen if to build both SAI/ESAI and IMX_PCM_DMA as modules at the same
time ?

I didn't find error/warning when SAI/ESAI and IMX_PCM_DMA are as modules. The 
build is successful.

Yes, but if IMX_PCM_DMA == m, the SAI/ESAI will be invisible in menuconfig....
Does it matter here ?

Having SND_SOC_IMX_PCM_DMA selected if SND_IMX_SOC is not selected makes no 
sense. I think the proper fix is to find out why it is selected and make 
sure that it is not selected when SND_IMX_SOC is not selected.

No, that has the dependencies in reverse.

I guess the issue happens if SND_SOC_FSL_ASOC_CARD=m and 
SND_SOC_FSL_{ESAI,SAI,SSI}=y. In this case the fix is simply to drop the 
select SND_SOC_IMX_PCM_DMA from SND_SOC_FSL_ASOC_CARD.

Yes, you are right. Thanks. I will send another patch.
