commit db9b60400f9253c25ae639797df2d0ff7a35d9d8 upstream.
We were getting build warning about: drivers/gpu/drm/gma500/mdfld_dsi_output.c:407:2: warning: initialization from incompatible pointer type
The callback to dpms was pointing to a helper function which had a return type of void, whereas the callback should point to a function which has a return type of int. On closer look it turned out that we do not need the helper function since if we call drm_helper_connector_dpms() directly, the first check that drm_helper_connector_dpms() does is: if (mode == connector->dpms)
