From 6bb18c9be6d256d7e8e24e7a676df2e2fd72522c Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 2 Jul 2020 13:50:26 +0200 Subject: drm/ast: Init cursors before creating modesetting structures The cursor helpers reserve buffer objects in VRAM and update their content. So although tied to modesetting, cursor helpers are more of a memory manager. The modesetting's cursor plane requires this functionality, so initialize cursors before modesetting. While at it, also add an error check for ast_cursor_init().
