[PATCH 20/20] device property: Implement fwnode_get_next_parent() using fwnode interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



fwnode_get_next_parent() can be implemented using fwnode interface. Do
that to avoid implementing an additional callback for the function in
struct fwnode_operations.
