+Subject: [PATCH] i965: Remove early release of DRI2 miptree
+
+intel_update_winsys_renderbuffer_miptree() will release the existing
+miptree when wrapping a new DRI2 buffer, so we can remove the early
+release and so prevent a NULL mt dereference should importing the new
+DRI2 name fail for any reason. (Reusing the old DRI2 name will result
+in the rendering going astray, to a stale buffer, and not shown on the
+screen, but it allows us to issue a warning and not crash much later in
+innocent code.)
