From 30634e8e41d413b0084ba29f843361a1fd9fbdce Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 5 Sep 2012 10:38:10 -0300 Subject: [PATCH] [media] sliced vbi: subdevs shouldn't clear the full v4l2_sliced_vbi_format struct Various subdevs cleared the full v4l2_sliced_vbi_format struct, when only the service_set/lines fields should have been cleared. Due to this the io_size field was wrongly cleared to 0, causing a v4l2-compliance error.
