In order to properly release the I2C adapter used for DDC/CI, use the i2c_put_adapter() function provided by the I2C subsystem rather than the put_device() function which doesn't include code to drop a reference to the adapter's owner module.
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);
