From 1f3f53ae5179ba7f24b4a429bc41773f1f4857ca Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sat, 17 Dec 2011 13:28:52 -0600 Subject: [PATCH] OMAPDSS: APPLY: fix NULL pointer deref when mgr is not set extra_info_update_ongoing() goes through all overlays, but doesn't check if the overlay is connected to a manager. This leads to a crash whenever an overlay has been detached. Add a check to skip the non-connected overlays.
