[v2,11/14] drm/ast: Init cursors before creating modesetting structures

Commit Message

Thomas Zimmermann July 2, 2020, 11:50 a.m. UTC

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().
