Yes.

It is already corrected at my -git tree and at V4L/DVB development tree,
available at http://linuxtv.org/hg. The correction is also at -mm
series.

This trouble were discovered too late at 2.6.18 cycle, and affected just
vivi module, used to emulate a v4l2 driver. It is likely to affect just
driver and userspace developers.
