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
