On sandbox it's possible to trigger NULL dereference when setting rate
of a composite clock. It happens because sandbox composite divider does
not implement set_rate() operation. This series adds NULL check and a
test cases for clk_set_rate().


Igor Prusov (2):
  clk: Check that composite clock's div has set_rate()
  dm: test: clk: Add test for ccf clk_set_rate()
