udev attributes to detect compress-offload devices

[Carlos Rafael Giani <crg7475@xxxxxxxxxxx>]

Are there attributes in udev that allow for unambiguously detect a 
compress-offload device?

Currently, I have the problem that I can't autodetect compress-offload 
devices reliably, because I see nothing in udev that identifies a device 
as such.

The next best thing thus far has to be to rely on the /dev/snd/comprC*D* 
name. But, these device nodes can be renamed, can't they?
