SYNOPSIS

struct device * driver_find_device(struct device_driver * drv, struct device * start, void * data, int (*match) (struct device *dev, void *data));

ARGUMENTS

drv

The device's driver

start

Device to begin with

data

Data to pass to match function

match

Callback function to check device

DESCRIPTION

This is similar to the driver_for_each_device function above, but it returns a reference to a device that is 'found' for later use, as determined by the match callback.

The callback should return 0 if the device doesn't match and non-zero if it does. If the callback returns non-zero, this function will return to the caller and not iterate over any more devices.
