The function's description talks about checking the writeback connector state, not the encoder state. Moreover, there is no such thing as an encoder state, encoders generally do not have a state on their own. Rename the function to drm_atomic_helper_check_wb_connector_state() and change arguments to drm_writeback_connector and drm_atomic_state.
