Subject: Re: [PATCH v2 2/5] unicore32: pwm: Use module_platform_driver()
> Some of the boilerplate code can be eliminated by using this macro. The
> driver was previously registered with an arch_initcall(), so technically
> this is no longer the same, but when the driver is moved to the PWM
> framework, deferred probing will take care of any driver probe ordering
> issues.
