Since it's too late for v3.4 now and we will get a new pwm
subsystem in v3.5, I suggest you change the driver to work
register with that subsystem instead of just using the old
header file. Note that drivers/mfd is not really the right
place anyway, because this is not a multifunction driver but
just one device driver that happens to be a slave of an mfd.
