krealloc potential issue

[Andy Shevchenko <andy.shevchenko@xxxxxxxxx>]

We don't want to assing result to old variable.

drivers/pinctrl/berlin/berlin.c:239:    pctrl->functions =
krealloc(pctrl->functions,
drivers/pinctrl/sh-pfc/pinctrl.c:192:   maps = krealloc(maps,
sizeof(*maps) * nmaps, GFP_KERNEL);
drivers/pinctrl/sunxi/pinctrl-sunxi.c:400:      *map = krealloc(*map,
i * sizeof(struct pinctrl_map), GFP_KERNEL);
drivers/pinctrl/sunxi/pinctrl-sunxi.c:1088:     pctl->functions =
krealloc(pctl->functions,


I have checked them, and seems all listed have a flaw.
