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") -- Cheers, Stephen Rothwell
