[CentOS] C7 Kernel module compilation

Hey there,
I'm trying to compile a single module following this guide:




I tried to compile a module for novuton led controller supplied by 
thirdparty and I got several error.

To check if this is the wrong procedure I tried to compile cifs module 
as listed in howto but when loading with modprobe I get "Exec format 
error", and from dmesg "cifs: no symbol version for module_layout
", the same errors when compiling novuton module and I don't know why I 
get this error.

I noticed that modules in centos are compressed in .xz but after running 
make M=fs/cifs I got only a .ko kernel module and then I run xz to 
compress the new module.

Can someone help me please?

Thanks in advance.
