    Subject[PATCH 2/6] unicore32: pwm: Use module_platform_driver()
    Date
    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.
