-Subject: pinctrl: sunxi: fix theoretical uninitialized variable access
-
-gcc warns about a  way that it could use an uninitialized variable:
-
-drivers/pinctrl/sunxi/pinctrl-sunxi.c: In function 'sunxi_pinctrl_init':
-drivers/pinctrl/sunxi/pinctrl-sunxi.c:1191:8: error: 'best_div' may be used uninitialized in this function [-Werror=maybe-uninitialized]
-
-This cannot really happen except if 'freq' is UINT_MAX and 'clock' is
-zero, and both of these are forbidden. To shut up the warning anyway,
-this changes the logic to initialize the return code to the first
-divider value before looking at the others.
-
-Fixes: 7c926492d38a ("pinctrl: sunxi: Add support for interrupt debouncing")
