NAME
class_for_each_device - device iterator
SYNOPSIS
int class_for_each_device(struct class * class, struct device * start, void * data, int (*fn) (struct device *, void *));
ARGUMENTS
class the class we're iterating start the device to start with in the list, if any. data data for the callback fn function to be called for each device
DESCRIPTION
Iterate over class's list of devices, and call fn for each, passing it data. If start is set, the list iteration will start there, otherwise if it is NULL, the iteration starts at the beginning of the list. We check the return of fn each time. If it returns anything other than 0, we break out and return that value. fn is allowed to do anything including calling back into class code. There's no locking restriction.
