Revision 0848814aa296ca13e4f03848f35d2d29fc7fc30c authored by Imre Deak on 05 February 2024, 13:26:31 UTC, committed by Joonas Lahtinen on 06 March 2024, 13:34:03 UTC
The DSC HW state of DP connectors is read out during driver loading and
system resume in intel_modeset_update_connector_atomic_state(). This
function is called for all connectors though and so the state of DSI
connectors will also get updated incorrectly, triggering a WARN there
wrt. the DSC decompression AUX device.
Fix the above by moving the DSC state readout to a new DP connector
specific sync_state() hook. This is anyway the logical place to update
the connector object's state vs. the connector's atomic state.
