Hi Guillaume

	20:22:15.060525  <4>[    9.948821] sysfs: cannot create duplicate filename '/devices/platform/sound/(null)-wm8904-hifi'

Hmm, I couldn't reproduce this.

I'm not 100% sure about kontron-sl28-var3-ads2, but it seems
below doesn't have .name, and I think no one add it to
sai->cpu_dai_drv.

	${LINUX}/sound/soc/fsl/fsl_sai.c :: fsl_sai_dai_template

Maybe it is the reason of naming "(null)" ?

And, if my understanding was correct, it is from fsl-ls1028a.dtsi,
and fsl-ls1028a-kontron-sl28-var3-ads2.dts.

If so, all sai1 - sai6 are using "fsl,vf610-sai",
all saiX doesn't have .name. I think it should have different name.
In your case, at least, sai5 / sai6 needs to have

	...
	sai5: .name = "sai5",
	sai6: .name = "sai6",
	...

Thank you for your help !!

Best regards
