[PATCH 11/17] drm/imx: imx-ldb: release ldb-channel resources within encoder destroy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no reason why the resoruces should be freed manually within the
component.unbind() call instead it is easier to use the drm-core destroy
helper. The destroy helper gets called for each registered encoder
during a drm_mode_config_cleanup() call.
