From 6cefa31e810404dafdfcdb94874146cea11626c2 Mon Sep 17 00:00:00 2001 From: Iskren Chernev Date: Sat, 2 Jan 2021 22:24:37 +0200 Subject: [PATCH] drm/msm: Fix MSM_INFO_GET_IOVA with carveout The msm_gem_get_iova should be guarded with gpu != NULL and not aspace != NULL, because aspace is NULL when using vram carveout.
