ALSA: hda: hdmi - preserve non-MST PCM routing for Intel platforms
Commit 5398e94f ("ALSA: hda - Add DP-MST support for NVIDIA codecs") introduced a slight change of behaviour how non-MST monitors are assigned to PCMs on Intel platforms. In the drm_audio_component.h interface, the third parameter to pin_eld_notify() is pipe number. On Intel platforms, this value is -1 for MST. On other platforms, a non-zero pipe id is used to signal MST use. This difference leads to some subtle differences in hdmi_find_pcm_slot() with regards to how non-MST monitors are assigned to PCMs. This patch restores the original behaviour on Intel platforms while keeping the new allocation policy on other platforms.
