Hans, I've had some patches pending for a while now that affect the dsbr100 driver. The patches can be seen here: http://desource.dyndns.org/~atog/gitweb/?p=linux-media.git in the dsbr100 branch. The first patch in the series fixes locking issues throughout the driver and converts it to use the unlocked ioctl. The series is a bit old, so it doesn't make use of the v4l2 core assisted locking; but that is trivial to implement after this patch.
