The driver is assuming a capture stream exists. My codec is output only.
While the driver declares a capture stream the core doesn't require that both capture and playback be available - it will cope with a capture only or a playback only DAI (this is fairly common due to DAC only and ADC only parts). Unless there's some other issue specific to this driver?
Yes, it GPFs allocating a a DMA buffer on the null capture stream pointer.
Where does it GPF? When dereferencing pcm->streams[x].substream in psc_i2s_pcm_new?
