mtk_build_eint is to add external interrupt function to the corresponding bound pins. mtk pinctrl driver still can work (than means probe() successfully) to keep pinctrl functional even with there is an error in mtk_build_eint. So the patch is used to explicitly free those data on failure in mtk_build_eint to let unused data is being free:ed immediately. thanks, Sean > If it is called on the probe path no explicit free:ing is > necessary: anytime probe() exits with an error code, > any devm* resources will be free:ed. > > Yours, > Linus Walleij
