Ugh.  I'm not against this patch, but which device(s) are we talking
about, and have you complained on the linux-media mailing list?  This
is likely something Hans can tweak in the framework to make sure a
driver *never* returns a stepsize of zero (i.e. make the v4l2
framework force the value to 1 if the driver says zero before
returning the ioctl call to userland.
