That patch fixes the issue(s). I didn't even need to revert 64df6afa0dab ("ASoC: Intel: broadwell: change cpu_dai and platform components for SOF") on top of that. But you can assess better whether that patch needs care for other reasons; for me, this one-liner you have suggested is perfect.
Good news!
.ignore_suspend is set for bdw-rt5677.c and bdw-rt5650.c as well. I don't know if that was intentional.
The intended use case is for applications doing audio during suspend like telephony audio between the modem and CODEC on a phone or compressed audio playback. I guess the compressed audio playback case could possibly apply with these systems though x86 suspend/resume is usually sufficiently heavyweight that it's surprising.
I think that's true, on many of SKL- intel platforms(byt, hsw, bdw), we are seeing this .ignore_suspend set with offload or deep buffer FE dai_links configured together.
So it looks we can't ignore calling codec's suspend/resume callbacks during the power cycle for rt286 codec(on the Dell XPS here), which is actually supported on Chromebook SAMUS(rt5677)?
