fsl_ddr_edac.c looks to be doing exactly what we are doing with
skx_common.c. They just get away with it for now because they don't
have a reference to THIS_MODULE since they don't set up anything
in sysfs.

If this is your goal, then Qiuxu's patch that moves the problem
piece out of skx_common.c does what you are asking for.
