[sane-devel] [pieusb] Fix unused-parameter compiler warnings

Hi Klaus,

The following functions in pieusb_scancmd.c trigger a pile of unused
parameter warnings:


Upon closer inspection, I noticed that these functions are not called
anywhere in the backend and all but the get-halftone-pattern are stubs.

I'm trying to get rid of all compiler warnings and wondered how to fix
this.  I can completely remove the functions from the code or mark all
unused parameters with a __sane_unused__ on the assumption that they
will be unstubbed and used in the (near?) future.

What do you suggest?

Hope this helps,
