DRIVER_FIND_DEVICE(9) Device drivers infrastructure DRIVER_FIND_DEVICE(9)NAMEdriver_find_device - device iterator for locating a particular device.
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.
