From bd40536ae33911bc74df5ba3b29b573dcb72f904 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Sat, 20 Jul 2024 16:25:22 +0200 Subject: [PATCH] drm/xe: Introduce const cast helper Typically we want to preserve pointer constness when converting from one xe pointer to another, but in some rare cases, like kunit parameter conversions, we might want to discard this constness. Add a helper that we will use to clearly indicate our intention.
