Just curious how you can enable config INTERCONNECT_QCOM as "m" (module)? I checked the config INTERCONNECT_QCOM which is dependent on INTERCONNECT, and INTERCONNECT has below dependency: - DRM_TEGRA [=n] && HAS_IOMEM [=y] && (ARCH_TEGRA [=y] || ARM && COMPILE_TEST [=n]) && COMMON_CLK [=y] && DRM [=m] && OF [=y] - TEGRA_MC [=n] && MEMORY [=y] && (ARCH_TEGRA [=y] || COMPILE_TEST [=n] && COMMON_CLK [=y]) Seems to me, it's impossible to enable INTERCONNECT as "m" because the dependency ARCH_TEGRA/OF/COMMON_CLK cannot be configured as "m". Thanks, Leo

Thanks for confirmation, Yiwei. > So shall we change INTERCONNECT_QCOM config to tristate? I personally think modularization is the right thing to do; to avoid misleading you, I would leave your question to interconnect maintainers. Thanks, Leo

Since icc-common.c can be compiled as module, add the missing MODULE_LICENSE to avoid compile errors.
