diff --git a/drivers/pinctrl/pinmux.c b/drivers/pinctrl/pinmux.c
void pinmux_free_setting(struct pinctrl_setting const *setting)
...
+ /* + * If a setting is active, disable it so that all pins are released + */ + pinmux_disable_setting(setting);
"*If* a setting is active ..." implies there should be a C if statement here to check if the setting is actually active before trying to disable it?
