[PATCH 3/5] clk: refactor of_clk_del_provider()

Show all headers | View raw

Now, it is guaranteed that a single node does not appear twice in
the list of OF clock providers.  So, of_clk_del_provider() only
needs to free the first occurrence.  This can be implemented more
simply with __of_clk_find_provider().
