BUS_FIND_DEVICE(9)                Device drivers infrastructure                BUS_FIND_DEVICE(9)



NAME
       bus_find_device - device iterator for locating a particular device.

SYNOPSIS
       struct device * bus_find_device(struct bus_type * bus, struct device * start, void * data,
                                       int (*match) (struct device *dev, void *data));

ARGUMENTS
       bus
           bus type

       start
           Device to begin with

       data
           Data to pass to match function

       match
           Callback function to check device

DESCRIPTION
       This is similar to the bus_for_each_dev 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.
