Signed-off-by: Douglas Anderson --- If this patch lands before the patch ("drm/msm: Avoid manually populating our children if "simple-bus" is there") it doesn't seem to be the end of the world. The first time through add_display_components() it'll notice that the children are already populated and it will be a no-op. When it gets a defer it will then depouplate them (even though it didn't populate them) and future calls will just populate them again. arch/arm64/boot/dts/qcom/sc7180.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/qcom/sc7180.dtsi b/arch/arm64/boot/dts/qcom/sc7180.dtsi index 2be81a2a1512..cae6c69fd85a 100644 --- a/arch/arm64/boot/dts/qcom/sc7180.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7180.dtsi @@ -2594,7 +2594,7 @@ camnoc_virt: interconnect@ac00000 { }; mdss: mdss@ae00000 { - compatible = "qcom,sc7180-mdss"; + compatible = "qcom,sc7180-mdss", "simple-bus"; reg = <0 0x0ae00000 0 0x1000>; reg-names = "mdss";
