Based on the discussion, I think you and Jani are right. It should be
in hsw_audio_codec_enable() and not in ild_audio_codec_disable().
else

IMO, it's better to have a macro to cover this two-line check instead
of open-coding at each place. We'll have 5 places in the end.
OK, I will use a macro.
Also, this patch still has an issue about the encoder type, namely, it
passes intel_encoder from MST, where you can't apply
enc_to_dig_port(). We need another help to get the digital port
depending on the encoder type, e.g.
static struct intel_digital_port *
intel_encoder_to_dig_port(struct intel_encoder *intel_encoder)
{
struct drm_encoder *encoder = &intel_encoder->base;
if (intel_encoder->type == INTEL_OUTPUT_DP_MST)
return enc_to_mst(encoder)->primary;
return enc_to_dig_port(encoder);
}
Yes, I will fix it in the new version patch.
