From dc64836942762c64b155729921acb2841570d16e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 11 Nov 2011 11:22:20 -0300 Subject: [PATCH] omap3isp: ccdc: Fix crash in HS/VS interrupt handler 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.
