From 2e57f47d317dd035b18634b0c602272529368fcc Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 17 Jul 2013 12:14:40 +0100 Subject: [PATCH] drm/i915: Fix dereferencing invalid connectors in is_crtc_connector_off() In commit e3de42b68478a8c95dd27520e9adead2af9477a5 Author: Imre Deak Date: Fri May 3 19:44:07 2013 +0200 drm/i915: force full modeset if the connector is in DPMS OFF mode a new function was added that walked over the set of connectors to see if any of the currently associated CRTC was switched off. This function walked an array of connectors, rather than the array of pointers to connectors contained in the drm_mode_set - i.e. it was dereferencing far past the end of the first connector. This only becomes an issue if we attempt to use a clone mode (i.e. more than one connector per CRTC) such that set->num_connectors > 1.
