[PATCH v6 3/3] drm/komeda: Fix IS_ERR_OR_NULL() vs NULL check in komeda_component_get_avail_scaler()

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

 



The komeda_pipeline_get_state() returns an ERR_PTR() on failure,
and a null is catastrophic here we should use IS_ERR_OR_NULL()
to check the return value.
