Oh, my patch is for linux-next 20160609 tree, can not apply to v4.7-rc2
directly.

After "grep -rn pr_fmt * | grep define" under arch/, for me, it is
blackfin's issue:

  we need use

    #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

  instead of

    #define pr_fmt(fmt) "module %s: " fmt, mod->name

I shall send one blackfin patch for it.

Thanks.
