When applied on linux-next-20120824, the patch failed because original
imx-ssi.c file looks like :
static struct snd_soc_dai_driver imx_ssi_dai = {
.probe = imx_ssi_dai_probe,
.playback = {
/* The SSI does not support monaural audio. */
.channels_min = 2,
.channels_max = 2,
.rates = SNDRV_PCM_RATE_8000_96000,
.formats = SNDRV_PCM_FMTBIT_S16_LE,
},
.capture = {
.channels_min = 2,
.channels_max = 2,
.rates = SNDRV_PCM_RATE_8000_96000,
.formats = SNDRV_PCM_FMTBIT_S16_LE,
},
.ops = &imx_ssi_pcm_dai_ops,
};
The comment line is missing in your patch. Here is the right patch :
