Which file did you use as template? Isn't this supposed to be reversed?
BTW, you *must* work on latest tree. Do not take some ancient code and
use as template. It's really waste of time to point the same issues over
and over again.

Why these are reversed comparing to other bindings? Srsly, from which
file did you take it?

Drop "cam_" prefix in both. Actually everywhere...
