From: Hans Verkuil With all the v4l2_subdev changes that were made to these drivers it is a good idea to increase the version number of each driver. It's just the patch level that is increased, except for the zoran and saa7146 drivers where the minor number was increased due to the more substantial changes that were made to those two drivers.
