platform_driver_probe()
platform_driver_probe — register driver for non-hotpluggable device
Synopsis
int __init_or_module 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
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.
Returns zero if the driver registered and bound to a device, else returns a negative error code and with the driver not registered.
