Revert "pinctrl: amd: Disable and mask interrupts on resume"
This reverts commit b26cd9325be4c1fcd331b77f10acb627c560d4d7. This patch introduces a regression on Lenovo Z13, which can't wake from the lid with it applied; and some unspecified AMD based Dell platforms are unable to wake from hitting the power button Signed-off-by: Kornel Dulęba <korneld@chromium.org> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Link: https://lore.kernel.org/r/20230411134932.292287-1-korneld@chromium.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
