+Subject: [PATCH] fb: properly wrap/unwrap CloseScreen
+
+fbCloseScreen assumes that it overrides miCloseScreen (which just
+calls FreePixmap(screen->devPrivates)) and emulates that instead of
+wrapping it.
+
+This is a wrong assumption, we may have ShmCloseScreen in the mix too,
+resulting in leaks (see below). Fix this by properly setting up the
+CloseScreen wrapper.
+
+This means we no longer need the manual DestroyPixmap call in
+vfbCloseScreen, reverting d348ab06aae21c153ecbc3511aeafc8ab66d8303

+Subject: [PATCH] dix: always initialize pScreen->CloseScreen
+
+CloseScreen is wrapped by the various modules, many of which do not
+check if they're the last ones unwrapping. This is fine if the order of
+those modules never changes but when it does we might get a NULL-pointer
+dereference by some naive code doing a
+
+ pScreen->CloseScreen = priv->CloseScreen;
+ free(priv);
+ return (*pScreen->CloseScreen)(pScreen);
+
+To avoid this set it to a default function that just returns TRUE that's
+guaranteed to be the last one.
