V4L/DVB (10644): v4l2-subdev: rename dev field to v4l2_dev
Hans Verkuil [Sat, 14 Feb 2009 15:00:53 +0000 (12:00 -0300)]
Remain consistent in the naming: fields pointing to v4l2_device should
be called v4l2_dev. There are too many device-like entities without
adding to the confusion by mixing naming conventions.
