[PATCH v2 1/8] drm/i915/pps: add vlv_ prefix to pps_pipe and active_pipe members

Jani Nikula jani.nikula at intel.com
Mon Sep 9 12:15:36 UTC 2024


The pps_pipe and active_pipe members of struct intel_pps are only
relevant on VLV/CHV. Prefix them with vlv_.

Note that there are still a few cases where they're accessed on
non-VLV/CHV paths. We'll fix them separately.
