Hi Wolfram,

That call is required in order to register the sensor device on the rmi 
bus, so that the rmi functions can be associated with it.  Without that 
call, the driver will not function.

I'm afraid I can't locate the commit you specified.  I do find a driver 
in staging/ste_rmi4/synaptics_i2c_rmi4.[ch] - is that the one?  If not 
which, tree/branch can I find it in?

					Thanks,
