drm_helper_disable_unused_functions — disable unused objects
void drm_helper_disable_unused_functions ( | struct drm_device * dev); |
This function walks through the entire mode setting configuration of dev. It
will remove any crtc links of unused encoders and encoder links of
disconnected connectors. Then it will disable all unused encoders and crtcs
either by calling their disable callback if available or by calling their
dpms callback with DRM_MODE_DPMS_OFF.
