FROMGIT: ALSA: hda/hdmi: fix max DP-MST dev_num for Intel TGL+ platforms Increase the device select range to 4 on platforms supporting 4 concurrent displays. This fixes a problem in scenario where total of 4 displays are active, and 3 of these are audio capable DP receivers and connected to a DP-MST hub. Due to incorrect range for device select, audio could not be played to the 3rd monitor in DP-MST hub.
