Yes, I have thought about that as well, but it can cause other problems.
I have modified the fftest tool from:
http://www.koders.com/c/fidF60D5962FCA8B937A6D0947AA81AE95A8C58FB36.aspx
for my needs.
It opens the /dev/input/eventX, and it will keep it open as long as it is
running.
It is OK for me, since the twl6040-vibra goes to low power mode when we do not
have effects running.
I can imagine, that real world application will do the same, and that might
cause some problems, if I try to zap the device.
Can we zap a device, while it is open?
How application will handle that event?
