[PATCH 17/17] staging: tidspbridge: remove nldr_init() and nldr_exit()

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

 



The dynamic loader was called by node.c with an interface. This interface was
also modified to avoid the use of nldr_init() and nldr_exit().

There is not functional changes.
