Specifically, these defconfigs will break as they all use PL111 but don't need nor enable VEXPRESS_CONFIG: arch/arm/configs/integrator_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/lpc18xx_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/lpc32xx_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/nhk8815_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/realview_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/spear3xx_defconfig:CONFIG_DRM_PL111=y arch/arm/configs/versatile_defconfig:CONFIG_DRM_PL111=y These defconfigs should all be failing with the same error, but don't from what I've tried nor have I seen any kernelci failures.
