PLATFORM_DRIVER_PROB(9) Device drivers infrastructure PLATFORM_DRIVER_PROB(9)

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.
