From a299e407b9ef356bf14fbb49793dc026877440df Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 6 May 2012 13:31:27 -0300 Subject: [PATCH] [media] av7110: fix v4l2_compliance test issues Besides the usual inconsistencies in input enumeration there was also a kernel crash if you tried to poll on a vbi node. The checks for sliced vbi output vs vbi capture were not complete enough.
