Is this a problem for the other users too? $ cd drivers/gpu/drm; git grep put_device | grep ddc exynos/exynos_hdmi.c: put_device(&hdata->ddc_adpt->dev); exynos/exynos_hdmi.c: put_device(&hdata->ddc_adpt->dev); panel/panel-simple.c: put_device(&panel->ddc->dev); panel/panel-simple.c: put_device(&panel->ddc->dev); tegra/output.c: put_device(&output->ddc->dev); vc4/vc4_hdmi.c: put_device(&hdmi->ddc->dev); vc4/vc4_hdmi.c: put_device(&hdmi->ddc->dev); ??
