    Subject[ 07/41] [media] omap3isp: ccdc: Fix crash in HS/VS interrupt handler
    3.2-stable review patch.  If anyone has any objections, please let me know.

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

    From: Laurent Pinchart <laurent.pinchart@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.
