From 641b9103d8383f52025bd2e1d3aaed2356efc913 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Mar 2020 15:49:22 +0100 Subject: drm: Manage drm_gem_init with drmm_ We might want to look into pushing this down into drm_mm_init, but that would mean rolling out return codes to a pile of functions unfortunately. So let's leave that for now.
