From 560c98b4a464215b04193c9ad7a4c07486ccf9c8 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Thu, 26 Jun 2025 11:02:31 +0200 Subject: [PATCH] drm/msm/a6xx: Get a handle to the common UBWC config Start the great despaghettification by getting a pointer to the common UBWC configuration, which houses e.g. UBWC versions that we need to make decisions.
