From a24ddee36ca10a90451552e6620ff7c4ff7e44b5 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 23 Oct 2008 09:53:56 -0300 Subject: [PATCH] V4L/DVB (9351): ibmcam: Fix a regression caused by a482f327ff56bc3cf53176a7eb736cea47291a1d As reported by David Ellingsworth: > I'm not sure if it matters or not, but the ibmcam driver in the > Mauro's linux-2.6 git tree in the for_linus branch is currently > broken. uvd is equal to NULL during most of ibmcam_probe. Due to that, an OOPS is generated at dev_info. This patch replaces uvd->dev->dev to dev->dev inside this routine.
