Removes the traces of the non-atomic helper calls in msm_pm_suspend/resume since we just deleted those functions (see patch 1). Also removes the drm_kms_helper_poll_disable/enable calls, since the DRM_CONNECTOR_POLL_CONNECT flag is never set so periodic polling doesn't happen anyways. v2: reorganized patch order v3: made error checks less severe Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Bruce Wang <bzwang@chromium.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
