3.2.77-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

commit dbb17a21c131eca94eb31136eee9a7fe5aff00d9 upstream.

Need to call this on resume if displays changes during
suspend in order to properly be notified of changes.
