Simon Ser af445f475a backend/drm: fix queued cursor FB overwritten with NULL ... With the following sequence of events, the cursor FB fields could end up being all set to NULL while the cursor is enabled: 1. set_cursor is called, conn->cursor_pending_fb is set to a FB pointer. 2. The output is committed with a buffer. crtc->cursor->queued_fb is set to the FB pointer, conn->cursor_pending_fb is reset to NULL. A page-flip event is expected in the future. 3. The output is committed with a modeset before the page-flip event is triggered. crtc->cursor->queued_fb is reset to NULL. At this point all of crtc->cursor->current_fb, crtc->cursor->queued_fb and conn->cursor_pending_fb are NULL which is a bogus state when the cursor plane is enabled. To avoid this issue, avoid overwriting crtc->cursor->queued_fb with a NULL pointer on commit. The cursor logic still isn't great, but let's keep a rework of that for a separate patch.
