From 2c93e7b7f545d2cca0e9e220ad7e6e1ac793ed39 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 19 Aug 2022 15:02:36 +0300 Subject: [PATCH] drm/i915: add initial runtime info into device info Add initial runtime info that we can copy to runtime info at i915 creation time. This lets us define the initial values for runtime info statically while making it possible to change them runtime. This will be the new home for the current "const" device info members that are modified runtime anyway.
