Hi Linus,

After merging the pinctrl tree, today's linux-next build
(arm_multi_v7_defconfig) produced these warnings:

drivers/pinctrl/sunxi/pinctrl-sunxi.c: In function 'sunxi_pinctrl_init':
drivers/pinctrl/sunxi/pinctrl-sunxi.c:1191:8: warning: 'best_div' may be used uninitialized in this function [-Wmaybe-uninitialized]
    div = hosc_div;
        ^
drivers/pinctrl/sunxi/pinctrl-sunxi.c:1128:31: note: 'best_div' was declared here
  unsigned int best_diff = ~0, best_div;
                               ^
drivers/pinctrl/sunxi/pinctrl-sunxi.c:1194:8: warning: 'best_div' may be used uninitialized in this function [-Wmaybe-uninitialized]
    div = losc_div;
        ^
drivers/pinctrl/sunxi/pinctrl-sunxi.c:1128:31: note: 'best_div' was declared here
  unsigned int best_diff = ~0, best_div;
                               ^
