[PATCH v2 4/4] drm/i915/dp_mst: Use intel_connector vs. drm_connector pointer in intel_dp_mst.c

Imre Deak imre.deak at intel.com
Tue Nov 26 16:18:59 UTC 2024


Follow the canonical way in intel_dp_mst.c, referencing a connector only
via a struct intel_connector pointer and naming this pointer 'connector'
instead of 'intel_connector', the only exception being the casting of
a drm_connector function parameter pointer to intel_connector, calling
the drm_connector pointer _connector.
