platform_driver_probe - register driver for non-hotpluggable device
2. SYNOPSIS ▲
int platform_driver_probe(struct platform_driver * drv , int (* probe ) (struct platform_device *));
3. ARGUMENTS ▲
platform driver structure
the driver probe routine, probably from an __init section, must not return -EPROBE_DEFER.
4. 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.
