The patch itself seems fine, but there are two issues around it:

* The PWM drivers should really get moved to drivers/pwm and converted to the new
  PWM subsystem. I don't know if Hartley or Hans-Christian have plans to do
  that already.

* Regarding the use of module_platform_driver_probe, I'm a little worried about
  the interactions with deferred probing. I don't think there are any regressions,
  but we should probably make people aware that one cannot return -EPROBE_DEFER
  from a platform_driver_probe function.
