| Series | [v1,1/2] pinctrl: make MediaTek pinctrl v2 driver ready for buidling loadable module | expand |

My proposal for the commit message: In the future we want to be able to build the pinctrl driver, based on paris, as kernel module. This patch allows pinctrl-paris.c the external interrupt controller mtk-eint.c and pinctrl-mtk-common-v2.c to be loadable as module. With this or something similar: Reviewed-by: Matthias Brugger <matthias.bgg@gmail.com> > > The following is the rationale for determining whether mtk-eint.c, > pinctrl-mtk-common-v2.c, and pinctrl-paris.c are built as loadable module: > > 1. drivers/pinctrl/mediatek/Kconfig: > 1.1 PINCTRL_MTXXXX: change from bool to tristate.
