linux-next: build warning after merge of the sunxi tree

[Stephen Rothwell]

Hi Maxime,

After merging the sunxi tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/clk/sunxi/clk-sun4i-tcon-ch1.c:82:6: warning: unused variable 'num_parents' [-Wunused-variable]
  int num_parents = clk_hw_get_num_parents(hw);
      ^

Introduced by commit

  4de2d58bc973 ("clk: sunxi: tcon-ch1: Do not return a negative error in get_parent")
