I was building the kernel module with the wrong gcc version.
I was using gcc version 4.9 instead of the original gcc-4.8 from Ubuntu
LTS Trusty 14.04.5
Sorry for this bug which wasn't one.

Found the solution here, I was building the kernel module with the wrong gcc
version.
I was using gcc version 4.9 instead of the original gcc-4.8 from Ubuntu LTS
Trusty 14.04.5 :
$ sudo update-alternatives --config gcc
Il existe 5 choix pour l'alternative gcc (qui fournit /usr/bin/gcc).
And these lines appear in dmesg log :
$ dmesg | grep -w wl | tail
[ 5704.013452] wl: version magic '4.4.0-121-generic SMP mod_unload modversions
' should be '4.4.0-121-generic SMP mod_unload modversions retpoline '
[ 5797.237082] wl: version magic '4.4.0-121-generic SMP mod_unload modversions
A little more info. to help :
$ sudo modprobe -v wl
insmod /lib/modules/4.4.0-121-generic/updates/dkms/wl.ko
modprobe: ERROR: could not insert 'wl': Exec format error
$ echo $?
1
$ sudo insmod /lib/modules/$(uname -r)/updates/dkms/wl.ko
insmod: ERROR: could not insert module
