clk: Fix incorrect return type in clk.c
Return type of function clk_propagate_rate_change is a pointer. But 0 was being returned. Change it to NULL. Silences the following warning: drivers/clk/clk.c:977:24: warning: Using plain integer as NULL pointer Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Reviewed-by: Pankaj Jangra <jangra.pankaj9@gmail.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
