DRIVER_FIND_DEVICE(9) | Device drivers infrastructure | DRIVER_FIND_DEVICE(9) |
NAME¶
driver_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¶
drvThe 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.COPYRIGHT¶
