Then other drivers based on the PWM driver can successully call old pwm_request because arch_initcall make sure the PWM driver will be registered earlier. Now, pwm_request is re-written and done by common layer code. It will return -EPROBE_DEFER if the PWM device is not probed. The driver based on PWM driver can make use of -EPROBE_DEFER to delay its probing. So arch_initcall can be replaced by module_platform_driver.
