The returned configs from pinconf_generic_parse_dt_config() is duplicated from original. Make it clear it must be freed when no longer necessary. Signed-off-by: Yingjoe Chen <yingjoe.chen@mediatek.com> --- It seems memleak in pinctrl-mtk-common.c[1] is not alone. After a quick glance I notice similar issues in drivers/pinctrl/pinctrl-at91-pio4.c and drivers/pinctrl/nomadik/pinctrl-abx500.c. I think it make sense to update document to make it clear it should be freed.
