+Subject: [PATCH 0189/2940] drm/ttm: Initialize local lists in
+ ttm_bo_bulk_move_helper
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The first parameter of list_cut_position() must point to an initialized
+list.
+
+Noticed thanks to KASAN pointing out something's fishy here.
