When HDMI PCM devices are opened in a specific order, with at least one HDMI/DP receiver connected, ALSA PCM open fails to -EBUSY on the connected monitor, on recent Intel platforms (ICL/JSL and newer). While

we don't have Ice Lake hardware support in the HDA HDMI codec driver in any 4.x stable trees (only in 5.1+), so this patch will not help on those and can be dropped.

Will do, thank you.
