This message was explained before, and I should have cited it: https://lore.kernel.org/all/aixze8zFboY3huSf@venus/ Sebastian writes there that it comes from one power-controller device providing all Rockchip power domains, and that it is not harmless: the kernel misses dependency information. So "harmless" in my commit message is wrong; the patch does not fix that, it only lowers the log level. It also lowers it for every other failure to create a sync_state-only link (found by the Sashiko review), which it should not. One such case is being fixed at its cause: on RK3576, Sebastian's "clk: rockchip: rk3576: create proper platform device" removes the lines for power domains with a clock phandle: https://lore.kernel.org/all/20261112-rk3576-clk-platform-device-v1-1-2f3ac9f09403@collabora.com/ Please drop this patch.
