If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai [ Upstream commit fe412e3a6c97cfe49ecf4564a278122f7d78e3f0 ] When EINT support for multiple addresses was introduced, the driver library for the older generations (pinctrl-mtk-common) was not fixed together. This resulted in invalid pointer accesses. Fix up the filled in |struct mtk_eint| in pinctrl-mtk-common to match what is now expected by the mtk-eint library.
