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, Chris
