Well, not sure it doesn't matter.
Before the device ID were swapped, my syslog reported :
     cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Error: ACPI _DSD
     Properties are missing for HID CSC3551.
And then, after the patch 51d976079976c800ef19ed1b542602fcf63f0edb, it
reports :
     cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Failed property
     cirrus,dev-index: -22
So, as it looks like a regression, it makes me think that the model name
may be checked along the device ID...

I already submitted that last one

Yes, but not smooth, as I have to workaround my broken mailer...
