Multiple users report a regression bisected to commit d5263dbbd8af
("ASoC: SOF: Intel: don't ignore IOC interrupts for non-audio
transfers"). The firmware version is the likely suspect, as these
users relied on SOF 2.0 while Intel only tested with the 2.2 release.

Rather than completely disable the wait_for_completion(), which can
help us gather timing information on the different stages of the boot
process, the simplest course of action is to just disable it for older
IPC versions which are no longer under active development.

[1/1] ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices
      commit: 9ee3f0d8c9999eb1ef2866e86f8d57d996fc0348

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
