 Ah, that has been sitting in drivers/staging for a long time.

 Does your modprobe work now?

 An example on Fedora 25 with a test module:

 ~/mymod> sudo modprobe mymod
 modprobe: FATAL: Module mymod not found in directory /lib/modules/4.10.5-200.fc25.x86_64
 ~/mymod> make
 make -C /lib/modules/4.10.5-200.fc25.x86_64/build M=/home/jsnitsel/mymod modules
 make[1]: Entering directory '/usr/src/kernels/4.10.5-200.fc25.x86_64'
   CC [M]  /home/jsnitsel/mymod/mymod.o
   Building modules, stage 2.
   MODPOST 1 modules
   CC      /home/jsnitsel/mymod/mymod.mod.o
   LD [M]  /home/jsnitsel/mymod/mymod.ko
 make[1]: Leaving directory '/usr/src/kernels/4.10.5-200.fc25.x86_64'
 xz --check=crc32 --lzma2=dict=512KiB mymod.ko
 ~/mymod> ls
 Makefile  modules.order  Module.symvers  mymod.c  mymod.ko.xz  mymod.mod.c  mymod.mod.o  mymod.o
 ~/mymod> sudo cp mymod.ko.xz /lib/modules/`uname -r`/extra/
 ~/mymod> sudo depmod -a
 ~/mymod> sudo modprobe mymod
 ~/mymod> lsmod | grep mymod
 mymod                  16384  0
 ~/mymod> dmesg | tail -1
