Subject: bridge: Elaborate a bit on dumb VGA bridges in Kconfig
Git-commit: bbce9ad9c26136a1581fa7cc6b576353b1a76ce9
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

It's better if we explain a bit that this pertains to
non-programmable VGA DAC bridges.
