> Since I haven't received any comments on driver code it should get merged. But I am not sure what the procedure is for input subsystem drivers? Is it happens through linux-omap or linux-input?
I'd rather see it merged via linux-input as that's where most
of the code is. The platform init code looks OK to me to merge
via linux-input too.
