driver_find_device - device iterator for locating a particular device.
2. SYNOPSIS ▲
struct device * driver_find_device(struct device_driver * drv , struct device * start , void * data , int (* match ) (struct device *dev, void *data));
3. ARGUMENTS ▲
The deviceAqs driver
Device to begin with
Data to pass to match function
Callback function to check device
4. DESCRIPTION ▲
This is similar to the driver_for_each_device function above, but it returns a reference to a device that is AqfoundAq for later use, as determined by the match callback.
The callback should return 0 if the device doesnAqt 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.
