The alert-slider is a tri-state sound profile switch found on the OnePlus 6,
Android maps the states to "silent", "vibrate" and "ring". Expose them as
ABS_SND_PROFILE events.
The previous GPIO numbers were wrong. Update them to the correct
ones.

Is there a reason it can't be the default 5ms, since it should
more or less be a simple input ping to the userspace?

Yes, it's a simple input ping to the userspace.
It works with the default 5ms also.

Thanks,
