Hi Ana,
If you have multiple files that make up a module, only one can define
the version, and that should be the one that has the
init_module/cleanup_module.
In the 'main' file with the init_module, I use:
#include <linux/module.h>
#include <linux/version.h>
In other files, that need to be linked with this, I use:
#define __NO_VERSION__
#include <linux/module.h>
#include <linux/version.h>
Regards, Stuart.
