Hello,

to be fair, I write how I solved my problem:

i have 2 files driver_ase.c and driver_ase.h.

Inside a .h file there was some declarations includes for kernel
headers used only by driver_ase.c.
This includes declarations make a problems during compile the service_ase.c.

In other words the problem is not in the kernel, but is my C (header)
kow-how  problem.

Sorry

Ciao
Vale

P.S. Make and Compile the kernel modules it's very hard! lacks a
coherent and updated documentation for non-experts.
