3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Pinchart <laurent.pinch...@ideasonboard.com>
commit bd0f2e6da7ea9e225cb2dbd3229e25584b0e9538 upstream.
The HS/VS interrupt handler needs to access the pipeline object. It
erronously tries to get it from the CCDC output video node, which isn't
necessarily included in the pipeline. This leads to a NULL pointer
dereference.
Fix the bug by getting the pipeline object from the CCDC subdev entity.
