Hi Pavel,

Hi!

quoted

ABS_SND_PROFILE used to describe the state of a multi-value sound profile
switch. This will be used for the tri-state key on OnePlus phones or other
phones.

Looks like ABS_PROFILE would be fine to use there, no need to create
new one, no?

ABS_PROFILE used by some Xbox game controllers to switch controller 
profiles. In the future, it's imaginable to play games in a linux mobile 
with the controllers. If we don't want to know in userspace where the 
event comes from, I think ABS_SND_PROFILE would be better.

Thanks,
Gergo

Best regards,
								Pavel
