In s5pxx18_pinctrl_set_state testing count to be negative will always fail as count is unsigned despite receiving the return value of a function that returns an int. Change count and idx to be of type int to allow the test to work as expected and remove the need for any implicit casts. Also change pin to be u32 which is what all called functions expect.
