Hi Richard

I don't know about the PTP subsystem, but in general, forward
declarations are frowned upon, and it is generally requested to
reorder the functions to remove them.

include/linux/platform_device.h:

/* module_platform_driver() - Helper macro for drivers that don't do
 * anything special in module init/exit.  This eliminates a lot of
 * boilerplate.  Each module may only use this macro once, and
 * calling it replaces module_init() and module_exit()
 */
#define module_platform_driver(__platform_driver) \
        module_driver(__platform_driver, platform_driver_register, \
                        platform_driver_unregister)
