RE: [alsa-devel] [PATCH V1 1/3] ASoC: fsl: Kconfig: remove dependence of SND_IMX_SOC for SND_SOC_IMX_PCM_DMA

Lars-Peter Clausen & Arnd

The purpose of Arnd's patch is same with me, which is to resolve the =

build

quoted

quoted

error when SND_SOC_IMX_PCM_DMA=3Dm & SND_SOC_FSL_SSI/SAI/ESAI/SPDIF=

=3Dy, the

quoted

quoted

error is "undefined reference to `imx_pcm_dma_init'".
But Arnd's patch didn't involve this situation that SND_IMX_SOC=3Dn &
SND_SOC_IMX_PCM_DMA=3Dm.

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

select SND_SOC_IMX_PCM_DMA if SND_IMX_SOC !=3D n

to

depends on SND_SOC_IMX_PCM_DMA !=3D m

How do you think about this?

What will happen if to build both SAI/ESAI and IMX_PCM_DMA as modules a=

t the

same

quoted

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 =3D=3D m, the SAI/ESAI will be invisible in menucon=
fig....
Does it matter here ?
