Thanks Dmitry.

While I tend to agree with this, in embedded systems this might (not 
certainly) cause issues. Embedded SW (middleware, high level) tends to take 
the underlaying HW as static.
Before I can do the dynamic input device creation/destruction I need to make 
sure that the userspace is ready for this.
I'm planning to address your concern regarding to twl6040, and at the same 
time I'm going to change the twl4030 vibra/MFD/audio driver to behave in a 
same way.
