[PATCH 2/3] drm/i915/bigjoiner: Refactor bigjoiner state readout

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

 



Don't call enabled_bigjoiner_pipes twice, lets just move
intel_get_bigjoiner_config earlier, because it is anyway
calling same function.
Also cleanup hsw_enabled_transcoders from irrelevant bigjoiner code.
