NAME
       platform_driver_probe - register driver for non-hotpluggable device

SYNOPSIS
       int platform_driver_probe(struct platform_driver * drv, int (*probe) (struct platform_device *));

ARGUMENTS
       drv
	   platform driver structure

       probe
	   the driver probe routine, probably from an __init section, must not return -EPROBE_DEFER.

DESCRIPTION
       Use this instead of platform_driver_register when you know the device is not hotpluggable and has already been registered, and you want to
       remove its run-once probe infrastructure from memory after the driver has bound to the device.

       One typical use for this would be with drivers for controllers integrated into system-on-chip processors, where the controller devices have
       been configured as part of board setup.

       This is incompatible with deferred probing so probe must not return -EPROBE_DEFER.

       Returns zero if the driver registered and bound to a device, else returns a negative error code and with the driver not registered.
