clk: max77686: Remove unnecessary NULL checking for container_of()
container_of() never returns NULL, thus remove the NULL checking for it. Also rename get_max77686_clk() to to_max77686_clk() for better readability. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
